I would actually rope everyone on the invite list in to help plan it. Hurray for email!!!
CC everybody (except the bride) and start an open conversation about ideas, plans, games, loves, hates, restaurants/bars/catering/potluck, surprise v no surprise, etc. As long as you make sure you let everyone know that you'll be making all the arrangements/doing all the work it'll take 5 minutes of their time and will be tailored to the people coming! MAKE SURE in the instructions in the beginning to tell everyone to "reply all". This keeps everyone up to date and they can only blame themselves. Hehehe. Plus you've just been excused of all the stress. Make it witty & funny and you're sure to get a ton of responses.
Good Luck!
