It is a friends daughter's 10th birthday on Monday and my boys got an invite to her birthday party this Saturday (4 days notice) The party is at "The Beachhouse" which is in Glenelg, and has waterslide, dodgem cars, mini golf etc etc. Anyway I said to her this morning that we'd go, and asked if there was anything to pay or if she just pays a lump sum, like play cafe's. I then find out that we have to pay $27 a child. I have 3 children that have been invited. Plus the birthday child would expect a present, and it is a 45 min drive each way from where we live.
We're looking at $100 for my kids to go to a birthday party, for 2 hours. Not including the cost of petrol. It is something we really can't afford as we're trying to save for $700 in car repairs.
Would it be okay to tell the mother we can't go now, due to the costs, after already saying we'd go.
