Amie:
If I can offer a suggestion... I think if you ask for random dates you'll find answers all over the place and much more work on your part.... and I'm sure you have other things to do! I think it might be better to choose three dates and take a poll as to first choice, second choice, third choice or "unavailable" for that date. See what wins in the "most preferable with fewest can't-make-it" ratio and you'll have your date.

I was President of a state association for four years and organized many gatherings and can tell you, you'll NEVER get everyone to agree to anything!
