We are looking to book a 3 night Wonder cruise for 10/16 - 19 for myself, husband and 5 year old son. Where is the best place to book? The online Disney cruise site? Do we choose our own room when booking? Any suggestions on choosing a room? Any other booking advice? Do we need passports? We are in Orlando and will drive to Port Canaveral. Anyone know parking price? I have congestive heart failure, are there docs on board? What if I have to cancel the cruise due to medical reasons? I know I'll have a lot more questions, I appreciate any feedback/advice, I am excited about planning this trip, but don't have a lot of energy. Thank you ALL! Love, juliah
