Dd's nursery nurse has offered to have dd over night at my house (6pm until 10am) as I am going to a ball that will go into the very very wee hours as it doesn't start until 10pm. She lives with her parents (she is 19) and is constantly saying she is glad to get away from her parents' home, so has offered to stay at mine instead of having dd at hers. I will be offering her my bed, obviously, as we only have two beds in the house, so myself and my date (ooh! Sorry, am excited as am an sp) will have to stay in a travellodge or hotel, but am getting really really worried about finances as it is so expensive when adding a hotel on top, but would feel bad waking her up and sending her home, which is the only other option. What should I pay her? Is £50 fair?
