What has everyone's experience been when traveling to Disney with someone on oxygen? My MIL was recently put on oxygen and may have lung cancer. We have our trip already booked for May to celebrate my husband's birthday and since MIL might be sick we don't want to cancel since it could be her last big vacation. I'm just concerned with traveling with the oxygen tanks.
I have had both great and poor experiences when traveling to DISNEY with O2. Are you all flying or driving? There are protocols one must following if flying. The treating physician of your MIL needs to fill out a form from the airline authorizing her to travel by air and with O2. Please contact the airline for further info.
If she has chain supplier ( apria, lincare) then she can arrange for delivery of O2 to the hotel free of charge. She should also make sure that she gets a oxygen supply kit (tubes, cannulas) as well for use at the hotel that way she can trash it when she leaves. I usually have Apria deliver me 20 m6's 4 e tanks and a stationary concentrator for use at night. The m6's I take with me to the park ( about 4 in a rolling back pack) and leave with first aid so that when I need to change them out, I can just go and get a room and cool down and change my O2. It is very relaxing and provides me with a much needed break from the heat and humidity.
Do you know how many liters of O2 your MIL is on

. That is going to determine how many bottles of O2 she is going to need in addition to how hot and humid it will be will you are in WDW

.
I know that when it gets hotter out and very humid, I have to bump up my O2 to meet my demands. It also means that I need to replace my tanks faster, so she needs to determine how many O2 bottles she is likely to require during that time

. My O2 seems to evaporate faster when there is a lot of humidity in the air

. Also, is your MIL on gas or liquid

I forgot to ask, I just assumed it was gas since you said tank but there are liquid tanks as well

. If she is using liquid O2 tanks, then she will need to make sure that she refills her tank before leaving for the parks and to keep checking the levels as liquid O2 evaporates way faster then the gas
I am not sure if your MIL intends to ride anything, but I have been able to take my m6's on every ride except RNC . I was able to use my portable O2 bag (shoulder strap) and hang onto it when riding anything. On some rides, I place it between my legs and hang on to it dearly while riding on, EE, BTMR, and Splash and space mountain.
Please make sure that she keeps her supplier information on hand in the unlikely event that she arrive to the resort and find that her O2 is a) not there
or b) held hostage and or given away to someone other then her
I am sorry to hear that she may have LC and I hope that you all have a wonderful and memorable trip
If there is anything else you will like to know , please feel free to PM me
