Hi! I am trying to convince my husband to do a Disney/Disney Cruise trip and also run the Princess 10K in February 2017. He is really hung up on the cost of a Disney Cruise and so I'm trying to convince him. We would either be doing a 3 or 4 day cruise. Which ships do you recommend? Also, will it be warm enough to swim on the ship and/or at the two stops? We will have a 4 and 6 year old. Thanks!
