We (my son and I) spent a week at Pop in Feb with my sister. We're returning for a couple days next month and it's my older son's choice when I bring him in Jan (we get his choice for 1/2 the trip and mine the other 1/2).
I've stayed in a couple moderates and before that 5 or so deluxes, so I 've been lucky enough to experience a wide variety of resorts.
The rooms have 2 double beds (or 1 king) and there is a small table. There was also room for me to wheel the stroller in and park it near the door. No, there's not lots of room and it would get cramped if there were 4 people plus a baby in a pack-n-play, but the 3 that we had in the room was fine. There was plenty of hanging space and we stashed the suitcases next to one of the beds and our dirty clothes and shoes under the hanging stuff (maybe a suitcase there, too).
How many people will be in the room? Have you stayed onsite at WDW before?
