Hello! I wasnt sure where exactly to post this, but I figured the ladies or Ettiquette almost always have good advice!
So, I have already selected a "date", and have already found the Venue. The date I would like is August 10, 2014.
My main concerns are that I want to go run and put a deposit because Im nervous that my date will no longer be available! lol I spoke with FI, and we first said we will go and put the deposit down in July (Goodbye July!

) Then he said in October, after we come back from our vacation in Israel. I think that October is to close to the date (if its still even available) and Im having a significant amount of people coming from Israel which I feel I would like to give them a definite date by October, while we are there- if not earlier so that they can begin to make arrangements as the tickets are very costly ($1,300 ++).
My FI also has family in Nicaragua that will also be traveling and I would also like to give them a definite date as they too will need to make arrangements.
So, what would you do?
UPDATE:
The deposit has been paid, and we have an official date!
He now understands and were on the same page!
Thanks ladies!
