The Colonnade Hotel’s iconic rooftop pool (RTP) is a place not only to swim, but also to party outdoors, high above the city all summer long. This is one of the few hotel pools that allows non-guests, but entrance is on a first come, first served basis, even for folks staying there. Lounge chairs are typically quickly snapped up, so you might want to rent one of their cabanas well in advance. There are morning yoga classes and occasional nighttime promotional events. On weekends, the pool is only open to hotel guests, condo residents and cabana renters.
