We always stay at Sago Cay and love it. We've also always overlooked the marina. It is very peaceful and quiet. Of course we loved being close to Gasparillas (which I think will be closed for your trip) and we loved being close the tables in front of the marina to watch the fireworks at night. Whichever building you end up in you will love this resort! BTW we have three children and they love it too - not stuffy at all the way sometimes people have the preconceived notion that GF is too formal.
