I am going to stay overnight in a different city to celebrate a friend's engagement. I was promised a bed for the night. I asked months ago if I should get a hotel room and was told no. Today I get a text saying I should bring a sleeping bag (which I don't own) as I will be staying on a airbed. I am as you can imagine, less than pleased. I'd have happily booked an hotel but now it's £100 last minute for a night. So basically I'll be buying a sleeping bag when I get there.
