The Disneyland hotel has the neverland pool. It should be plenty warm enough to swim. It might not be warm enough to sun bathe next to the pool after getting wet. We have swam in the area in just about every month- Feb, March, May, Aug, Oct, Dec. Its always been ok. Some visits we have rushed back to our room a little quicker to others.
we live an hour from Disneyland and we have a pool in the backyard. There have been a few days this year where we've been able to use it. Usually by Memorial Day (end of May), we use our pool on a regular basis. So I think you'll be fine!
Thank you all! I'm sure my kids will be willing to jump in regardless of the temp, lol. I was more worried about myself, as I usually am "too cold" to get in until the water is 90 degrees (born n raised AZ girl) hehe.
I was there in december and the resort hotel pools are warm any time of the year. I was surprised they weren't cooler. I actually commented to my GF that the pool (at the Paradise Pier) was too warm for swimming (I was considering doing laps before bed) but that was ok too as i just chilled in the hot tub.
