Bachelorette party ideas?

Well first thing is, usually you don't plan parties in your own honour. Has someone offered to plan this? Also you're not getting married for a year, so it's early to plan right now.

Having said all that, if you're expecting people to pay you definitely need to check their budgets first before you plan anything and keep your expectations within that.

Hope it all works out for you!

I would be concerned about the weather in Ohio in late May. It is still quite cool then, and the waters are likely to be very cold still.
