I’m thinking a cruise would be infinitely more convenient and less stressful for everybody involved.
Less medical risk also with no pressurization.
It’s rare but loss of cabin pressure does occasionally occur and it could very well turn into a full blown medical emergency if not outright fatal.
A real bed to sleep and real restrooms for the disabled and real meals and real entertainment.
And it’s probably less then half the cost.
im trying not to be facetious but this sounds a lot like “I want I want I want” without regard of what you’re asking from others around you.
Maybe time to tell her it’s not the days of the Titanic anymore.
