I can find very few reviews about the Boulevard Pool at Cosmo. The Boulevard Pool is the regular pool (i.e., not Marquee Dayclub) at Cosmo. My group typically stays at the MGM. We are mid 30s and are older than 95% of the people at Wet Republic. So we spend the day at the MGM regular pool (particularly the lazy river). Our primary focus at the MGM regular pool is chatting up ladies. We do not go to lay out, talk to each other or get hammered (we drink but we usually remain coherent). We are contemplating staying at Cosmo on our next trip (later this summer). Cosmo has 2,995 rooms. My guess (wild ass guess) is that Marquee Dayclub can hold 1,000 people. Do the rest of the Cosmo guests go to the Boulevard Pool? I assume that the Boulevard Pool gets very crowded. That's what we are looking for - very crowded pool scene. I have to believe that a number of folks on here have spent time at the Boulevard Pool. Any reviews would be very appreciated.
