We loved Hojo's and would stay there again in a heartbeat! It was definitely warm enough to swim, 90 degrees almost all days we were there. However, october is iffy for LA, so it's hit or miss. We didn't go in the pool so I have no idea if it's heated. We only played at the waterpark area at the hotel. Check their website, I bet it tells you there. PS- More to come hopefully tonight.
