It is not OK for you to ask me to pay 200+ dollars to attend your bachelorette party. You are my good friend, and I want so badly not to disappoint you, but your party plans have put me in a position where I have to be a pooper and sit this one out.
The day-trip sounds like a LOT of fun, but I wonder if we couldn't have as much fun in a manner that does not involve driving 5 hours down Rt. 95 on a Saturday in August to go to an amusement park and stay in a "spa" hotel for an evening.
And yes, I realize that "you" are not in control of this situation, as your bridesmaids have taken it upon themselves to plan the party as etiquette dictates. But you could have set a price limit of, say, a hundred dollars? Or maybe even less, considering that in the 10 years I've known you, you've never had more than 20 dollars to spend in an evening.
Let's go out for a night on the town! A nice, reasonable, night on the town. It'll be fun!!
And I won't have to save up for it for weeks beforehand.
I love you! Have fun at your party!
