Well, after our first trip to Florence/Pisa (just returned today), I would definitely like a little bit of a slower-paced trip. We ran and did all the hotspots in Florence and Pisa over 2 days/48 hours. Pisa was more enjoyable because there were less things to do, so we were able to enjoy it a bit more (and it being cheaper than Florence was a plus). It looks like we only get flights to Belfast and Dublin, so we're aiming to stay in one and use it as a base for day trips and such. We're still debating between Belfast (Giant's Causeway is on that list) and Dublin (BrĂș na Boinne on that list). Or, can we travel between the two (we're looking at flying in late Friday night and back Monday evening, so that gives us three days of action).
