We were just on the Magic form Galveston during the 1st week of October. The days spent at sea were GORGEOUS! We wore our swimsuits all day and our son enjoyed the mickey pool. We are going on the Magic again from Galveston in January and are wondering if the temps will be comparable. This time we will be doing the 8 night Bahamian. Will it be too cold to enjoy the decks? We are from Oklahoma and would love 80's temps the entire time! What about Disney World in January? Do I need to pack a coat for my 5 year old son? Thanks!!!
