Playpennies

My son only attends nursery two days a week, Monday and Wednesdays. On Wednesday last week they let me know there would be no nursery this week Wednesday, but that he had to go to a totally different venue on Thursday this week for their Christmas party and that I had to pay entrance and for his snack at the party soft play place.

Can they just DO that? I now have to make alternative childcare arrangements for Wednesday, then have to arrange to GET to this place for Thursday, AND pay for the privilege? I don't want to complain, because they already think I'm a scrooge because I haven't written 30+ Christmas cards for the other three year olds in the school.

Am I being unreasonable though?
