[100th in 2015: Done!]
Located in the Cosmopolitan Resort and Casino, the Bamboo pool is a welcomed change from the typical party hard Vegas pool scene. It is very spacious; however, a much smaller scale than a lot of other pools in the area (e.g., Mandalay Bay) and also much more quiet. When staying at the Cosmo, if you are in the mood for some real R&R in the sun, Bamboo should be the pool choice for you (1 of 3 on-site).
After several visits to Bamboo, I've never had a problem finding an open lounger. It is indeed crowded, but not at over-capacity...no need to show up at 8am to secure a spot - thankfully! The gem on the 14th floor has some grassy (turf) areas, lots of beautiful, tall (fake) palm trees, a good sized rectangular pool, lounge chairs about, including some that actually sit inside the sides of the pool to help beat the high Nevada heat.
There is low volume music streaming - no "boots and pants and boots and pants" here. Also, a very diverse crowd - people of all shapes and ages.
Poolside service is friendly and fast. Bamboo offers drinks and light fare; both a little high priced, but that's to be expected. "Charge it to me room please. Or better yet, that guy's." ;)
