My husband and I just booked a trip for next May after seeing some great flight deals and are trying to figure out our itinerary. We don’t really enjoy art museums but do enjoy natural and history museums. We enjoy visiting historical sites and viewing architecture. So with that in mind here is what we are thinking:
Monday- fly out of Miami 
Tuesday- land in Barcelona at 8:30 am 
Wednesday- Barcelona 
Thursday- Barcelona 
Friday- Montserrat. Night in Barcelona 
Saturday- fly to Granada in am. Stay in Granada. 
Sunday- Granada 
Monday- train to Sevilla 
Tuesday- Sevilla
Wednesday- Sevilla 
Thursday- train to Madrid. Use as a base for day trips. 
Friday-  Segovia 
Saturday- Toledo 
Sunday- fly homefrom Madrid. 
I thought using Madrid as a base would be great to see the historical areas but with the understanding that we won’t see much of the city. Any changes you recommend? We are both in our mid thirties and don’t sit for long. I added a day more in Barcelona than I originally planned for time adjustment.
