Hi,
I am a fellow Sleep Apneac and have been taking a CPAP to WDW since 2003. I'll try to answer your questions...
On the Airport. I always carry the CPAP as a carry-on and have had no problems. A few times I've had top open the case and they have swabbed the CPAP for nitrates but that is about it. Just give yourself a few extra minutes to get thru security otherwise no problem.
At WDW. I've had a few problems that I'll decribe later but overall its not been a big deal. We have had to do some creative unplugging to get the CPAP plugged in and sometimes it's not on the side of the bed I'd like but its not been a major problem. I carry a plug that converts an outlet to 3 outlets, a short extension cord is also not a bad idea but not normally necessary.
The Challenges:
1. If your CPAP has a humidifier, you will be hard pressed to find any distilled H20 on Disney Property. If you absolutely have to use a humidifier you either need to take some distilled water with you or pick some up on the way to WDW. I can go without a humidifier for a week so I actually purchased a smaller, non humidified CPAP for traveling. Best thing I ever did...
2. This one is VERY important if you travel to WDW in the Fall. We found out the hard way last year. There is a Florida State mandate that all the hotels in Fla. do an emergency power test in the Aug-Oct time frame. During this power test there will be no power in the room, just emergency power to the lights in the hall. We did not find this out until the day of the test at 11pm at night when we returned to the Beach Club to find the message on our phone. The need for a CPAP at night was clearly noted on the reserveration. The manager informed us that all their emergency power units were loaned out and they could not get another that night. What they did was to move us for the night over to the Yahct Club as they were scheduled to have their test the next night. They appologised for the last minute notice and comp'd us the room for the night. So If you travel in the fall, you may not be able to find out when the power tests are to occur (the State may control that), be sure to note that you need a CPAP on your reservation and the you will need an emergency power unit if the power to your room is to be interrupted.
3. I had an issue on our first trip where housekeeping made up the bed and moved the bedside table a little ways away from the bed. This was when I still traveled with a humidified CPAP and I managed to turn over and pull the CPAP off the table and it lodged itself betweent he bed and the table. It landed in a position that allowed the water to flow back into the CPAP which shorted it out with a large BANG! Of course this was the night of Sept 11th 2003 so we awoke out of a deep sleep to a flash and a big bang...... CPAP was kaput so I called my Sleep Dr. and they Fed-ex'd out a loaner. I purchased a non-humidified travel unit after this.
Remember to note that you need to use a CPAP when you make your reservation, if you need a non-smokng room that will help.
Hope this helps, if you have any other CPAP questions, I'll be happy to take a shot at them.
