I have spent all year getting my Campervan fixed and back on the road ready to go camping over the summer holidays, spent loads on extra camping gear that dd has asked for (new awning with extra bedroom as she won’t share the van, comfy air bed as she wants to be more comfortable, cooking equipment etc...etc..), have spent ages researching different sites to make sure they have WiFi and electric hook up because she can’t live without it. Booked one site and waiting to hear back from another, was feeling excited so told dd about how lovely these camping sites are and that they have WiFi etc..., she looks up and declares that she hates camping and doesn’t want to go 
I am a single parent, so it’s just me, her (15) and her sister (13), her sister is severely autistic and although i could camp with just her sister it won’t be much fun as she’s almost no verbal and likes to wander off, she would also be lost without her sister as they get on really well.
Am IBU to make dd1 go? I just feel angry that dd1 didn’t say anything earlier, she’s been with me whist I have bought all the extra equipment to make her camping experience more comfortable, she knows how much I have spent and how hard I have worked to pay for it all.
I have offered for her to take a friend but she says she hasn’t got many friends and her best friend is busy. I can’t really leave her home alone as she has Aspergers and dyspraxia, she can’t cook and needs prompting to remember to wash/brush her teeth. I could leave her with her dad but he’s not really responsible enough (left her with him before and he didn’t remind her to wash, didn’t help her brush her hair, and she was a mess when I got home).
Is she just being your typical grumpy teenager, do I just insist that she comes and hope she enjoys it once we get there?
She has ruined many a holiday over the years by refusing to do any activities and sulking. I bought the Campervan in hope it would make things easier as she would have a mini home from home and we could stay at quieter places for a couple days at a time. Both trips I have booked are only for 2 or 3 nights.
