Stumped for where to kill time, Tim M. and I furiously searched online for cheap day pools. Blu really did the trick for us! We waltzed in for free (not sure we were that special, but it made us feel sneaky) and snagged a few lounge chairs pretty easily around 3pm on a May Tuesday. We stayed until the sun went behind the parking structure.
I definitely liked how non-pretentious the pool was. The crowd is very "come as you are" and perhaps more on the older side, at least on this day. But I definitely liked the chill factor. There's a nice ledge on the longer side of the pool, which faces the setting sun and is perfect for hanging out.
Sure, it's not super classy. You hear and see the monorail every 5 minutes, and the view all around isn't particularly stunning. Oh, and the birds sound wacko. But if you want some over-priced drinks and an easy place to hide away, this spot is definitely a good choice.
