Some people, you give them an inch and they take the ruler from you and beat you with it.
I think probably about half the fault is yours for just being too nice to people, unfortunately.
If I were in your situation, and I never end up in your situation because I"m a cast iron you know what and have no problem telling people, sorry, no, you can't behave like a two year old, I'd just call everyone, tell them that due to work changes/conference rescheduling, the whole vacation's off, and then re-plan it from scratch with just you and dbf.
The more people you have with you on the vacation, the more exhausting it is, and that was with people we wanted to vacation with in the first place.
