Hi, If you're going on a hot holiday or live in a hot place try and make you sure you have access to an outside pool to keep your temperature down, if heat affects your MS. However an important point to consider are handrails for entry and exit from the pool. It might be easy getting in, but getting out when you are tired is different. Check if the pool has a handrail into the water and steps or just a ladder. You could check photos on Tripadvisor or if not ring the pool complex/hotel/where-ever. It will make a world of difference to you. Being stuck in heat is not good.
