Any tips (Special things to pack/see/do) during Madrid/Andaluscia trip in mid-April

I was there in May and it was so much hotter than I thought it would be... not sure about now.
I loved this area and one thing we did on a whim was to go to the musical Carmen. We saw some posters and it was being held in the bull fighting ring, so we bought tickets and went.... it was different than the Carmen we knew, but it was amazing and in the open air arena with a full moon... One of those unexpected wonderful experiences. I think this was in Antequerra. We also went to a small restaurant outside of Malaga and had a cooking class, and then enjoyed our paella dinner. There was also a hike in a beautiful national park.
We also ended up at a local festival in Antequerra. We found out that the families all have their own tent and they cook their food and gather with their friends and family. We happened to get invited to join one of the groups but there were plenty of generic things that were open to everyone... lots of ethnic costumes, music and dancing.

That sounds amazing. Thank you for sharing!

Definitely check the temperatures for your destinations a few days before you depart, so you can adjust your packing if necessary. I was there in September and it was hotter than I expected. I got a lot more use out of my short sleeve shirts and a lot less use out of my long sleeve ones, and my sweater stayed in my suitcase. Of course, weather being what it is, you should always have at least one outfit for colder and one for hotter than you think it will be.

There's nothing special you need to bring for Spain. And if you did forget something or need extras, the easiest place is usually the El Corte Ingles stores. It's a department store, but the larger ones also have supermarkets and pharmacy sections. So, if you need sunblock, ziplock bags, or garbage bags (I needed these in Barcelona - don't ask), just head there if you don't know of a closer supermarket or pharmacy. Rick lists their locations in his books.

Speaking of which, if you're not checking luggage, you will likely need much more sunblock than you can take in a 3-1-1 bag. And if you are checking luggage, don't forget sunblock!

We just got back and it was pretty cold. Well, I guess I would say the weather fluctuated quite a bit. So check it before you go - we had warm sunny days for capris and sandals, and some days I was very happy I brought my rain jacket, jeans and boots! And yep, I still fit in a carry on (though not on the way home!).

Have fun! We LOVED Spain!!

You and your husband sound alot like my husband and I! We loved Sevilla the most. It is such a great city and so walkable. As far as clothing, don't worry too much! Madrid and Sevilla, especially, had great shopping, so you can always buy something you need there.

For Sevilla, definitely walk over to Triana. During the day you can go shop for ceramics and and it has great nightlife and restaurants. We found a couple restaurants by chance and had some of the best food of our trip there! One we really loved was Las Golondrinas.

My husband and I are soccer fans and the highlight of our trip was going to soccer matches in Barcelona and Madrid. We saw Real Madrid in Madrid, but I heard that the Sevilla stadium has a great atmosphere. It would probably be easier to get tickets in Sevilla as well.

Enjoy your trip! Get ready to walk...ALOT!
