Great service.
We stayed here Wednesday, March 14th - Friday, March 16th. This was during Texas Spring Break. We booked our room on Hotwire. 
For whatever reason, via Hotwire I could not select room type. There were 2 adults & (1) 5 year old in our party. We were booked in a king size room. Since they were sold out, we had to make due. Holiday Inn only has 4 roll aways & they were all in use. However, Robert at the front desk, did contact other hotels in area to location us one, but was unsuccessful. 
Every staff member that we encountered was very friendly & helpful. Robert was were friendly & as helpful as he could be with the roll away situation. He greeted each person coming & going the front desk area. 
We did use the indoor pool & hot tub. They said the pool was heated ; I thought it was cold, but the kids didn't mind at all. The hot tub was nice. 
Our shower had poor poor water pressure. Our a/c the first night, I thought it wasn't working, because we were hot. But would wake up cold, then hot, then cold???? Not sure what the deal with it was. 
Overall we were pleased with this hotel. Great proximity to Sea World. Friendly staff. Typical free breakfast fare. Nice restaurants around to eat.
