Hi, First Cruise for us coming up in November to celebrate our 40th wedding anniversary so I have lots of questions!! Going on the Fantasy for 7 days to Western Caribbean. An important question I have is about bringing my CPAP machine on the ship for my Sleep Apnea. I need to use Distilled water in the humidifier and guess I will need at least a gallon jug. May I bring the water on board myself, or is there a place that I can get it once on the ship? Also, I've heard that there could be electrical outlet shortage. Can you tell me what length extension cord would be a good one to pack? Thanks!!
