Went here on vacation with my teenage boys. We have stayed twice before at Summit Watch so we wanted to give Mountainside a try. Love the location right on the mountain, making it easy to walk to the lifts, slides and trails. All the amenities are very accessible i.e. the pool, fitness center, movie theater and game room.
Staff are very friendly and helpful and they make you feel welcome. The rooms are clean and nice and the property seems well-maintained. We exchanged a week through Interval and would have preferred to have a larger unit (for some reason they only exchange the studio units for points and will not allow an upgrade even though there was no way this place was sold out. Would be nice to have the option to upgrade with points or cash if you're listening Marriott...)
Anyway, so I would have given this property 5 stars if not for the disaster of a parking situation. We stayed for a full week and our car had to spend 3 of 7 nights in the overflow lot which is quite a hike from the resort and not at all convenient when you're carrying things up to the room. A little advice for future travelers: If you are getting back to the resort after 11pm and the parking lot is flashing the red full sign- try anyway there are usually 3 or 4 spaces left.
Despite these concerns we will definitely be back. It was very quiet and relaxing.
