My Ds uses a cpap machine at night to help him sleep since he has sleep apnea. I have already talked to Disney and they sent me a medical form to get filled out by his doctor so we can use it on board. They even said they could try and get him a small side table to put it on. We are booked in cat 5 so I know we could use the coffee table if disney couldn't get another smaller table. My question is: I know you can only carry on 1 bag per person and my kids each will have a back pack and my husband and I will each be using a carry-on. The machine actually comes in a back pack so do you think they will count that towards the number of bags? I don't want to check it through since we have to have it. Don't want it getting broken or lost.
