Two Choices. Live with it or Put Your Foot Down. by: Eunice
No matter what, she should not have the right to access your tickets and reservation. You should take it up with the airline and your timeshare and ensure that they did not do it again.
Regarding the pet, if it says no pets allowed, then it is not the matter of 'solving the problem' because you are sharing the space with others. There must have been a breakdown in communication with your daughter because it sounds like she has been doing things behind your back or without your knowledge.
Yes she is right that she can do whatever she wants as a 40 year old, but definitely not to your timeshare and your tickets because you own them. Let her stay in her own place if she holidays with you the moment you realize she wants to bring her dog. It may not be pleasant but either you 'make do' with her inconsiderate behaviour, or you make a stand and put a stop to it.
I don't think there is a right or wrong because all families have issues with each other from time to time and we ALL have to make one of those choices.
So take that into account, accept her behaviour and try to live as happy as you can with it, if you can't, then you'll have to kick up some fuss.
All the best. You are definitely not alone in this.
