Last summer we spent four days at the Great Wolf Lodge in the Pocono Mountains, and we had a terrific time!  We stayed in a "KidCabin Suite," so the bunk beds where the kids slept looked like a cabin from the outside!  The bunk beds are still in the same hotel room, but they had a little more privacy (and so did we!).  Not to mention they had their own t.v. in the "cabin."  The waterpark was great-not too much and not too little.  There was a lot for smaller kids to do, including their own smaller pool, and there was a lot for big kids too.  The whole place is full of families, so noise isn't something you're worried about (but the hotel rooms are very quiet).  We checked into the hotel on Monday, and out of the hotel on Thursday, and we felt like it was exactly the right amount of time.  Any longer and we would have been looking for things to do outside of the hotel.  The food is a bit pricey, but that was our only complaint.  It's a great family destination!
