We are traveling to Spain next April with our two kids (they'll be 4 and not quite 2). We are seasoned travelers, as is our older child (although none of us have been to Spain). We're visiting a relative studying abroad in Madrid. We're flying into Barcelona for the first portion of the trip, then taking the train to Madrid, then train to Bilbao and flying home from there. We have multiple nights at each location, so won't be rushing through. I have a couple of specific questions:
I was not planning to bring the kids' car seats. Is this a mistake? We won't rent a car, and will use public transportation. Will this present a problem trying to get from, say, the airport to the city center? Or maybe someone has done this before and can suggest a car service that would be able to transport all of us and that has car seats for those few times we'd need them? Of course, we can take the train from the airport to the city center too. In particular, our flight from Bilbao leaves pretty early, so I'm not sure the bus service will work (it doesn't begin to run until 5:15 a.m.).
Any particular ideas on kid-specific things to do? I'll be researching the heck out of the trip over the next six months, but any ideas would be great. I've read about the Chocolate Museum in Barcelona and we'll obviously be going there!
If anyone has ideas on good areas to stay in each city, I would appreciate it. We are going to do AirBnBs or apartment rentals. Ideal location would be a nice neighborhood, relatively close to public transportation (particular the main train station for going from Barcelona to Madrid and then Madrid to Bilbao. If it's also close to some of the main sites, even better, although we like to walk a lot.
Thank you all in advance. I'll probably have follow up questions!
