we had the same scenario in April. We had our swimsuits in our carry on bags and spent the early afternoon at the main pool. We just called the front desk every once in a while to check to see when our room was ready -- then quickly unpacked our bags and headed off to Epcot for the evening! That way we felt we got in a full day on the first day! Since it was April, and we are from Ohio - the pool was a very welcomed sight!
