If it's not pool weather in Las Vegas while I'm visiting...I'm a sad panda.
I don't gamble much so I really embrace my pool time while visiting. Of course the weather when I visited last week was in the high 80s/90s and had to drop to the 70s while I was visiting, though it was better than Chicago so time to embrace the pool weather! I wouldn't go to the pool when it's 70 here in Chicago but 70 has a different feel in LV.
Pool Day 1 - 70/71 degrees...chilly wind but when the wind wasn't blowing, it was just perfect because it CAN get too hot here, hot when you don't even want to leave the pool. I've visited in July & August so I know what that's like. There wasn't a cloud in the sky so this was pretty close to perfect! We arrived late morning/early afternoon and told that the bar wasn't open due to the wind, but we could bring in drinks from the Mirage. Later on we just ordered from our waitress but that was a nice option. The waterfall wasn't on either...due to the wind. It was still a great day - not at all crowded where you had to get down first thing to save yourself a chair. The size of the pool is just great (way better than the size at Treasure Island). It's about 3 1/2 feet throughout.
Pool Day 2 - mid to high 70s though overcast for a while but still a great pool day! The waterfall was on this time and just great atmosphere here.
The drinks are a bit steep in price - almost $20 for a large beer, $14 for a strawberry daquiri but you're on vacation so just go with it...
