Hi Tink!
We went in October when the twins were 5.5 months old. We're also DVC owners and seasoned WDW vets with babies/kids.
My tips...
- Use a baby carrier. On the buses, I would wrangle both babies and having one in a sling while I carried the other was a lifesaver. Or I would have a baby in the sling, carry the diaper bag and a stroller, and watch my daughter.
- We brought our double stroller, which we needed for the airport. The concourses are so vast, it's hard to manage without. We used the most compact double that we own-- the combi twin savvy. It has a carry strap so it was easy to use on the buses. We had a single combi for our daughter too.
- Have a separate diaper pack. A ziplock bag with diapers, wipes, disposable changing pad. It made it easy to just run into the bathroom to change diapers without lugging the whole diaper bag in.
- You won't be able to bring your double stroller into the baby care centers, so if you plan on using one, don't go alone. I made this mistake and then was kind of stuck in parade crowds.
- If your babies are used to cribs, you can ask for them at the DVC resorts. I called and requested two on my reservation. Then when we checked in, we asked again. You don't have to use pack n plays. Be specific that you want a crib, not the pack n play in the room. The cribs are smaller than standard size ones.
- If the babies use lovies (animal, blankie), sew a address label on-- or even just your phone number written on some ribbon. I nearly lost one of ours at the airport but found it on the janitor's cart. I was able to positively ID it b/c of the label.
- Pack light! You'll have a rental car, so anything needed can be bought. You have washer/dryers avail so take advantage of it. We had a 2 BR, so our w/d was in the room. I ran a load in the morning and at night. I layed out all the clothes I thought we'd need and only packed half. I am usually an overpacker, but I was determined to go as light as possible.
- Gate check your car seats if you're not using the aboard the plane. Use large clear garbage bags or those car seat bags for them. The seats will be handled much more gently than they would going in regular luggage. And there's less likelihood they'll be lost too.
- If you didn't buy seats for the babies, make sure they're registered with the airline for your flights.
- For the plane, we brought bottles, food, new toys, extra formula, baby blankies, extra pacifiers and baby carriers. You can't wear the babies during take off and landing, but we did use them while we were in the air. Our arms were much less fatigued.
- Bring any baby meds you might need. I know you'll have a car, but it's always good to just have some infant Tylenol or Motrin in your diaper bag if needed.
- Stroller fans were great! Even if it's not too warm, the fans really helped with air circulation.
Take it easy. Don't expect to do much. It rained a lot on our trip, but we still managed to have a great time. I stayed with the babies most of the time, strolling around. I was just happy to be there with them. My husband took our 5 year old daughter on rides, so we often split up.
PM me if you have any questions... I've rambled on enough.
