It's my sister's 2nd wedding in May, which she's having in Cyprus. I persuaded my husband to shell out £600 to go for 3 days for the wedding, with the promise that, other than the wedding itself, we would spend the time together having a little break in the sun. I've already been persuaded to go to their hotel the night before for drinks, now she wants me to go in the morning (to help get her ready? Or look after her kids?Dunno.)Incidentally, we'll be the only 2 on her side going as the rest of my family can't afford it/ too old to make the trip. Now she tells me that a friend of her future MIL has already arranged the hen night in a town a couple of hundred miles away and the idea is that we'll 'crash' at this woman's house overnight. There are a couple of issues for me here- one, I am a 'troubled sleeper' and dread staying in a strange bed where I'll have difficulty sleeping, especially after a heavy night out. Two, I don't have anything in common with these people apart from my sister, which adds to my concerns re 1. Lastly, I feel a bit miffed that, having paid out for the trip abroad, I'm also now epected to pay out for this trip (petrol etc.) Am I being really horrible?
