We stayed there 2 nights in August. We LOVED it.
The reviews for Nick Hotel were not that great. I went with no expectations, and was pleasantly surprised. My kids are a little older then the average kids there (DS 11 DD9), but they had a BALL!!! We were there 2 nights which was about 2.5 days and to me, that was plenty of time. We stayed there the whole 2 days and did all we could at the hotel. Mostly we sat around the pool and had drinks while the kids swam! They also have shows, shops, little classes like painting, pottery etc....
