Re: Marriotts in Park City comparison and booking availability (by Sandy H):
I can only answer part of questions. To compare the two locations. We've stayed many times at Marriott Summit Watch. We like that it's a bit more quiet, that's it's in town, close to the restaruants, and seems to attract more adults than families. We've been there in July, August, and September; but not during the ski season. If you like action, activities, or will be traveling with kids...I would think you would prefer Mountain Side, even in summer they have lots of activities and access to zip line, hiking, pool etc. If you like walkability to restaurants for the evening, and won't be traveling with kids, would think you'ld like Summit Watch better. Summit Watch is a much smaller resort.
Best of luck.
