see if you can get a room with balcony - so you can sit out in the sun while baby is sleeping inside. Flat ground is good if you are pushing a buggy around. Not too hot and not too noisy (you don't want baby woken up by disco music all night). No point in keeping baby indoors all day but be very careful about sun on his skin, it's very very tender. Baby probably won't be walking by then but if so you'll have to keep your eyes open for unprotected stairs and balconies and furniture with sharp angles.
Don't want to put you off but as tigwig said, it won't be like the holidays you've been used to!
