In regards to the deposits,Try these tips, they seemed to have worked for me:
1. Send out email/blog posts showing them how to make the deposit and remind them that there is 6 days left to book. Mention that the hotel could sell out and the rates may increase if they wait to book after your due date. ( this really happened to my mom's friend who got married in Cancun)
2. Give a shout out to everyone who has booked on Facebook and tag them, this will remind other people to book their trip.
3. Have your sister or close family friend reach out to family members and close friends who really should be booking and have them send a friendly email saying that if anyone has any questions contact me, we really hope to see you all there, etc.
4. If anyone is having "trouble" booking, have your travel agent or planner (if you're using one) contact them directly to resolve any issues
I hope these tips help! Its SO STRESSFUL, I KNOW.
For the dress, I'm still considering renting, so I'm near LA and we're going to take a trip to Korea Town to their bridal district to see what they have. The Pronovias dress I'm looking at converts to a mini dress.
