WhiteFace is a blast - I have gone twice before. Both times I have stayed in Lake Placid. I would recommend this, as there are a lot of cool restaurants and bars etc. I stayed at the Holiday Inn (I think) the first time I was there. They had a hot tub and it was right down town and right on the lake as well - very cool. But with 10 people that may get a little expensive. The second time I went we rented a townhouse also right on the lake for six of us the prices were great for three night divided six way I came out to 50 bucks a person per night. Can't beat that. There was not hot tub though the palce was really nice it was three floors two bathrooms and three bedrooms with a pull out couch and full kitchen. I think the site I found it on was www.lakeplacidlodging.com
or something close to that. If you search around the lodging info for lake placid (not on the whiteface page) you should be able to come across it. It think they did have some places with hot tubs, but we went for the price savings. Any way hope that helps. Oh you mentioned the slides - I usually never see those things open until March! I try to keep an eye out for when they open them. Unless there is a freak snowstorm early in the year - which is not normal for Whiteface - at any rate it is not often so ski if you can when you go. They were open the first time I went up like five years ago on the second week in March but I didn't go because I was skiing with some friends who were intermediates but not ready for the slides. I went up again two years ago on the third weekend in March but they hadn't had any snow and it was in the 60s. I think they got dumped on the next week and opened the slides up. Just my luck.
