Melissa--regarding Stratton, it was always an upscale place so if it's more so now must be uh..."interesting". We're about 14 miles south of Bethel/Sunday River. Be happy to share our experiences of Maine although we've spent most of our time in western Maine since my wife has transferred her intense focus from skiing to horses.
Kelly--Wells, yes, that's the civilized part of Maine. Kennebunk and Kennebunkport are great fun, stayed there (in one of those Victorian houses) for a weekend. Also great spots to visit are Freeport (home of L.L.Bean, open 24/7/365) and Camden. Camden is really a wonderful traditional seacoast village with a harbor full of old schooners and fishing vessels. Haven't been to Bar Harbor in ages but it was very nice last time I was there. So, happy to assist in travel planning whenever you're ready
