Long story but every year or two a relative has taken us on holiday with them for a variety of reasons including them not wanting to travel alone out of the UK and also to give us a holiday when they knew we couldn't afford a holiday otherwise. Obviously we brought our own spends and bought meals and a present etc and I am extremely grateful.
Last year DD who is now a teen started an activity which in fairness she does love but she started kicking up a fuss about going (which again she is a teen so I understand she might not want to go on holiday with us anymore ) but it was because it meant she would miss her twice a week sessions. Relative very kindly tried to book around the sessions as she didn't want to go without DD but needed the dates for the camps and DD was an utter pain in the backside getting these. She didn't say so much she didn't want to go (which again as a teen I would understand) but made it as hard as possible to book anything because relative wouldn't book without the camp dates and DD took forever getting them. I tried to get them but as the emergency number is for the venue not the club and due to her age I don't have much contact so was unable to.
Fast forward to now and quite rightly said relative has given up and quite rightly used the money elsewhere to buy a vehicle they can go away in alone without worrying about hotels and travel on planes/trains on their own. I'm not moaning at that at all. I'm glad they have.
The consequence of this however is that DD is on two already paid for camps, one 3 days, one 10 days and also a lovely trip away and is going on
and on about how amazing camp is going to be and what fun she is going to have and I'm stuck at home and/or work with no break at all for the foreseeable future and I'm a bit pissed if I'm honest! 
I know I'm unreasonable to be cross but aibu to be just a little bit peeved.
