I have a few questions! We are going on the 7-day Mexican Riviera cruise on the Disney Wonder. 1. Are there refrigerators in the room? We are carrying on our own alcohol to help off-set the cost. 2. Dress code for dinners? I know there is a formal and semi-formal night so I want to make sure I pack correctly. I can't find the itinerary for this cruise. 3. My husband is using a cane because of an injury, should I fill out the disability form? 4. Do we have to present the credit card on checking in? Or is it just based off the information we entered? Thanks in advance for the help!
