Italy vs Spain in June

Whichever has the easiest connection. Neither fits your itinerary well, but as the crow flies Italy is closer. Check flight or train times. If you choose Spain, try to fly into one and out the other.

If your itinerary is in the order you’re visiting places, then pick a place between Jungfrau and Prague like Salzburg or Nuremberg. Rather than spending so much time getting to places, stick to a location in northern Italy and spend more of your limited time enjoying the location rather than getting to it. I love Andalucia but it’s a long way from Switzerland. Traveling with an infant shouldn’t be an issue. We took our son on a 21 days European tour when he was 10 months old and he didn’t prevent us from seeing what we wanted to see.

Edited to remove a portion I misinterpreted from the OP’s question.

When you're not flying between places, what modes of transportation will you be using? If not renting a car, CT has convenient train and boat connections, along with walking trails, if you're thinking of trekking between villages. Doing that without an infant or young child in tow would also seem to give CT an edge in your planning for this trip.

Andalusia is a lot of ground to cover, if you're not driving yourselves (and even if you are, it's big), so unless you're going to stick to, say, Granada, Spain wouldn't be well-suited for your 4 days this time around.

Happy travels!

jaimeelsabio - Not sure how you felt the we are just want to check off something from our list. hope you understand the gist instead of reading between too much and dissecting words. Allocating 4 days isn't like touch and move situation and I don't believe in spending a month at a place as I am not a historian. I guess you need to learn how to respond or can refrain from replying.

Yeah I have to agree. There are so many beautiful places within the area you will already be. You will spend so much time getting to and from airports and getting through security that you won't get a real feel for anywhere, just a surface postcard tourist experience. What about the Rhine or elsewhere in S. Germany, or Ardennes, or Bruges or Ghent. Having been to all the places you mention, I dont think a quick jaunt to either region would be very satisfying. But if you're committed, I would choose Italy bc the climate is a little less harsh in summer, esp. as you'll be on the coast in the CT.

Thanks Cyn and Jessica. Point regarding CT totally makes sense.

Better to visit Andalusia in cooler weather.

I don't know about Italy, but June in Andalusia will be hot! I went in April to Seville and Granada and on some days it already got up to almost 70 and walking around the Alhambra in that heat sounds awful. Plus both Italy and Spain love their child so you probably will get better service with the child:)

I'd find a spot further north-Germany maybe?

Both Andalusia and Italy may be very hot in June.
If you are coming from Zurich and later intend to fly to Amsterdam, Florence May make more sense. Florence airport and/or its neighboring airports (Pisa or Bologna) probably offer more flight connections to both Zurich and Amsterdam.
Also, if 4 days mean 3 nights on the ground, 3 nights (2 full days) would be ideal for Florence. If you have 4 nights you could squeeze Cinque Terre too. If you don’t have a 4th night maybe you could do a day trip to CT from Florence.
Andalusia is a big region. If you have 3 nights you could visit Sevilla only. Even if your intention is just to check off a list, squeezing both Seville and Granada in 3 nights would be a challenge because of the logistics involved in moving from city to city. GND doesn’t really have a lot of flights to too many places. Chances are you have to fly in and out of Seville and Granada and Seville are over 3 hours apart (no flights between the two)

Thanks everyone for such helpful responses. We have dropped Andalucia for next time due to time and weather considerations.
Roberto da Firenze - We will be reaching on Jun 13 (morning) in Florence and will have 13, 14, 15, 16 and would leave for Prague on 17th morning. With this much span, do you suggest being in Florence all 4 days and going for a day trip to Cinque terre or would we be fine staying one night in CT. Though it doesn't make much difference just gives few extra hours of being late in CT instead of rushing back to Florence. Thanks

I thought you were going to Amsterdam afterwards.
It appears you are going to Prague instead.
That presents another challenge, because only Bologna has non stop flights to Prague.
Depending on the time of flight departure from Bologna, you might need to spend the last night (June 16th) in Bologna. Bologna airport is over one hour from Florence (35 min train to Bologna Central, then shuttle bus or taxi to airport for 25 min). You can spend the last night in Florence if the flight from Bologna to Prague is late morning or after noon. Check the flights schedule as it may not operate daily. Ryanair and Czech Airlines fly from Bologna to Prague.
Whether you want to spend the 4 nights in Florence and visit 5Terre for the day, or want to split nights between Florence and Cinque Terre is up to you based on your preferences.
For sure the Cinque Terre is too far from Bologna, therefore you cannot stay there the night before flying to Prague.

Since CT is known to be busy full of day trippers, why not stay a night to see the quieter side? Besides, in my opinion, nothing is nicer than at evening by the sea and June would be heavenly.

My wife and I are going to the Naples area this year and I'm starting to plan for a larger tour of Italy next year.
When I see photos of the Tuscan countryside I say "that's nice"
When I see steep hills (Alps) or San Marino I say "I want to go there"

There are so many differences between us all :-)

I'd also 'stay' (go to) Florence, etc., rather than Spain (timing). I've been watching Rick's videos of the area. You probably know all about them, but here's a link: https://www.ricksteves.com/watch-read-listen/video/tv-show

Also, I think they have shorter segments on YouTube.
