We just had a 1 night stay at YC and DID find swimming relaxing, but approached it against the usual pattern. Arrival day (2:00 check in), we suited up, explored the amazing pool for 2 hours, and then changed and moseyed to Epcot for 3 rides, dinner, and a walk around WS. Very relaxing, even with a sort of busy pool. Day 2, even better, we went swimming when the pool opened at 9:00. There were about 4 other families in the enormous complex. We chatted with many lifeguards, enjoyed all areas, including slides with no lines, got out 2 hours later, and moseyed to Epcot for 1 ride before departing at 2:00. This probably doesn't work on a commando trip, but this was a bonus day with no agenda, booked a few nights before we arrived. Swim first, it's awesome! Kids aged 3,7, and 10, by the way.
