We never do this: just hang out by the pool all day on vacation. We did this day, such a novelty.
I can't recommend the Sheraton in Mt. Crested Butte. A king mattress fits across two twin box springs, but the hotel doesn't spring for king-sized pillows or king-sized fitted sheets or even fitted sheets at all or indeed sheets that aren't pilly. We didn't sleep well during our stay: the least movement untucked the minimal tuckage, just for starters.
There was a pool, smallish and not particularly cleanish, with a fine view of the butte, without shade. But that's me: it's a pool, and I would have preferred to laze the day away by a creek or a pond. But even fake water is better than no water. I explored the beautiful old Victorian village in the morning, checking out books from their library (in super old building that was a school until nine years ago) and shopping a bit, and then joined RDC by and in the pool. I stood in five feet of water, arms and chin on a towel on the deck, and read Second Summer of the Sisterhood.
There are worse ways to spend a day.
