It depends what you mean by "open." Will they be accesible? Yes. Will they be heated? Maybe. If the status of the pools is important to your decision-making process, you may want to call the hotels and confirm. Bill
It all depends on the weather. We were in Vegas last year over the weekend of Oct 21. It was hot and the pools were open. I am hoping that they are still open for our upcoming trip. But its a crap shoot (drum roll please)
That late in Oct., the real question will be if it's pool weather. From my experience in trying Oct trips, it's doubtful. Mid 70's in the desert is too cool for pooling it...at least to me.
Different property but last year i was at PH for thanksgiving week and the pool was open, i went thereto read almost everyday , never seen more than 8-10 person per day, no service no employees except for lifeguard
