Hi Peter,
Welcome to the Disney Parks Moms Panel! Thank you for bringing this question to us!
Since our girls are dairy free, we are often looking for dairy free milk as well! I just called 407-934-3400 to verify, however. The cast member I spoke with said they do have dairy free milk in the gift shops at the resort. If I were you, I would have the milk delivered to the resort. Garden Grocer is a popular delivery service in the Orlando area. Just be aware of the size of the refrigerator in your room. When we stayed at Disney's Caribbean Beach Resort, our room had a mini refrigerator.
I also suggest that you contact
Special Dietary Requests. If you send them an email to Special.Diets@DisneyWorld.com, let them know about your son's soy milk needs. Also remember to make a note on your dining reservations. We have found the cast members to be quite helpful at every restaurant!
Peter, you will love
Disney's Caribbean Beach Resort! Just be aware that the resort is undergoing refurbishment. Also, make sure you take a look at one of the online maps and locate a building close to the dining areas, main pool or a bus stop (depending on your preference). I would suggest Trinidad North, Building 31, Martinique, Building 26, Jamaica, Building 45 or Aruba, Building 51. Also, when you check-in to the resort, be sure to ask about the order of bus stops. You do not want to be the last to board when you are heading to the parks!
The walking/jogging path and the playgrounds around the resort are lovely. Enjoy!
Magic, memories and Minnie Mouse hugs,
Donyell
