It may not be a guilt trip. They may just want to be sure their dad has considered the cons as well as the pros before changing resorts. We have very few details regarding their trip to go on, and only one side of the dilemma. It could be that he is guilt tripping the family to get what he wants and the OP’s objections are completely valid.
The OP mentions an extended family trip, which could involve more than one cabin. We don’t know. If their dad has mobility issues and doesn’t want to use any type of mobility device, moving to a resort where there may not be any extended family to assist him should he need it is a valid point to bring up. He may not be aware that there is only one bank of elevators or how long the hallways are. There is a big difference in having your car right outside your cabin, and having to walk long distances just to leave the resort (I have stayed at both many times). Has he stayed at either resort before? Does he hate FW for some reason?
If they have their discussion and the dad insists, then I agree he should stay where he wants if he is paying the bill. In our family, the person paying for the room always gets the final vote. But by the same token, the rest of the travel party should not have to uproot their plans to accommodate one person who may be in stubborn denial about their ability to get around on their own. It’s possible that the OP has stayed at BW and doesn’t like it at all, and if he was going to be sharing their cabin, now there is an additional expense unless they all move. Is that fair to the OP?
If he were using an
ECV to help with his mobility issues, then having him stay at BW while the rest stay at FW would not be a big problem. My mom embraced the use of mobility aids but my dad fought them to his last breath, so I can sympathize with what the OP may be going through. Hopefully after they talk, there will be some compromise from both sides.
I was actually surprised that long walk at BW was only .2 miles. It feels so much longer at the end of the day . . .
