We stayed at the HJ Maingate East (I think) next to Water Mania in March 2000.
It was OK, but I would not go back.
Because we travel from the UK, this is a big holiday for us and we really want a bit of comfort. The hotel would be OK for a few nights for a cheap holiday, but we were hoping for something a bit nicer.
The room was old-fashioned and felt damp. We could hear people snoring next door. It was my first stay as an adult in Florida, and I didn't like the outside corridor setup, I prefer to be inside a building (if that makes sense) as I feel safer, especially as at that time there was a lot on the news about shootings in Orlando. (Although the highlight of the holiday was seeing an armadillo in the grass outside our room - never seen one before!)
The hotel was situated on the 192, behind a petrol station, and we felt the area was a bit tacky.
We still enjoyed our holiday, but would not go back to a HJ. However, I know it was closed for refurbishment after we were there, so it may be different now.
