I have been on the Dream and Wonder with my cpap machine. I sent in the Special Needs medical form a few weeks before our cruise stating I would be traveling with my cpap machine and having a long cord power surge bar with i.
On the form I noted I would need to have distilled water. The distilled water was already in the cabin when we arrived for one cruise, the other cruise it was there before dinner. The time it was not waiting for us the host explained the guest services had those type orders and would be bringing the gallon of water down. They always said to let our stateroom host know if we needed more so he could pass the work along to them. Probably couple of extra steps/papers they have to handle since these are considered medical supplies.
They have never questioned my long cord power surge bar but I pack in the same case with the machine. I haven't needed on the ships but have needed in the hotel rooms we stay in before and/or after the cruise.
Depending on what cabin I'm in sometimes I have to rearrange the bedside table to have room to hold the machine; hose with mask gets draped over the light during the day. We had a great stateroom host and he made a small towel animal, looped the hose around his neck and made it look like he was going to inhale from the end like a smoking pipe. It was cute.
Enjoy your cruise!! I'm counting the days until my next one.
