I am staying in Treasure Island Hotel, Las Vegas and from reading some of the messages, the pool does not seem all that great. As I will be staying in Vegas for a week, will any other hotels on the strip allow me to pay to use their hotel pools.

Any info would be appreciated

I'd say no. The ones that I knew that charged all stopped and limited access to hotel guests. But you might be able to get into Flamingo's for free. Nice pool, but crowded with screaming kids. I heard they might allow public access, check with them though.

You can always go to a waterpark.

I believe Monte Carlo lets you pay a day fee for use of the pool. But I wouldn't do it because it's not that great.

TI's pool is fine. It doesn't have all the bells and whistles, but it surely is better than say MGM, Trop, Luxor, etc.

Rent a cabana for a couple of days - then the pool will seem like heaven.

Don't worry, son. You go to Vegas, you'll pay. Everyone always pays in Vegas.
