Before I get into the nitty-gritty details, I want to put a disclaimer out there that I am aware this trip is tricky to do in the amount of time we have. However, my grandma is coming to Europe for the first time (and maybe her only time ever) and she really wants to fit in certain places.
Right now, the itinerary looks like this:
May 7-9 Paris (leave to Spain 9th night or 10th morning)
May 10-12 City in Spain. Currently debating between Seville and Valencia because I have wonderful things about these two cities. I think Seville would be great to feel like we are in Spain, but the beaches in Valencia are stunning. I have been to Madrid twice and do not really want to go again, and I do not think Barcelona is a great option for my grandma. If there are any other cities in Spain someone recommends, please let me know.
May 12-14 Rome. I know this is not enough time in Rome, however, I have visited the city twice now and plan on just booking tours instead of wandering around. Vatican one day and chill, and then I'm thinking of the bus hop on hop off or a vespa tour.
May 15-16 Venice. I am sad I will not be spending as much time in Venice as I would like, I am also willing to take this off the list if someone believes it would maximize our time in other places. I was hoping to visit Venice and use it as our relaxation time.
May 16-19 London. I am not a huge fan of London and my grandma knows nothing about it, so this is mostly for our Harry Potter fix.
We have to start in Paris and end in London as we have already bought those tickets, and she wants to go to Spain (anywhere) and Rome. I acknowledge this is crazy, if anyone has any recommendations without telling me I am crazy that would be much appreciated. Especially any recommendations for hotels, tours, restaurants for Seville/Valencia and Venice.
Edit: I am reading comments and yes, I did look at flights, that is why I started to have this dilemma because it was easier to get to Seville then get out of it. I usually try to leave at night so that we still have half a day to spend in the city we are currently in, and then land in the next city at night and go to sleep. I have also found that airports in Europe security lines are nothing compared to the US and getting there 2 hours early is a bit unnecessary. However, i have only been traveling here during the off-season, so I will still err on the side of caution.
