We stayed at Maingate east last March, and now that Ive read about HIFS, Ill be paying the extra $$ to stay ther on our next trip. Maingate east has kids suites, but it is just a sectioned off corner of the room... the other part of the room had a king bed and that was it.. At Hifs, there is an additional room (with couch and TV). The breakfast wasnt free at Maingate east, and the kids didnt eat free with one paying adult at the food court. Also, although my kids loved the pool at Maingate east, there was a wading pool for my 2 year old too....they will go nuts (I think) over the zero depth entry pool at HIFS. Maingate east offered a kids program, and that was one of the reasons we went there, however once we arrived, they told us the program was bring revamped, and so many of the activities werent offered....Maingate east does have 2 room suites, and had I not heard of HIFS, I may have returned to Maingate east and stayed in a 2 room suite(which is more $$ than a kids suite) . so taking that into account, the HIFS rate isnt too bad (even in Canadian $$). Also Im hoping for our trip next Feb. that there is another great offer like they had this year..(2nights for 1 rate).
