Yes, they are. My wife is only 5 ft tall, so she takes an inflatable chair. We have also seen large inflatables there before. Someone brought an inflatable bull one year.
During our last trip we saw a unicorn riding an inflatable alligator in the pool. Now, you're probably thinking, "Oh boy, the day drinking really got to them". Ha, no, we met her later in the hot tub but by then she'd lost the 'gator, which was fine because apparently it had eaten her inhibitions.
They are cute to see and a must for some of the shorter ladies....buttttt its the last thing you want bumping in you and your drinks. Specially those hugeeee ones that it takes 4 people to move off you....Talking from experience..♀️
