Hello and congrats.
I didn't do STD. I booked my resort in May and deposits to hold their spots were due in July.
What I did was send out my invites mid May, then sent reminder emails/texts/calls about 1 and 2 weeks prior to the deadline.
What I did for my RSVP date is made it the deposit deadline date. So the travel agent told my guests that deposits were due July 17 so that was also my RSVP date. Sneaky her, the true deadline was Aug 1, so if anyone had troubles, etc. they had a saving grace. We didn't tell anyone that though!
So personally, I would probably send your invites out ASAP and make the deadline whatever the date is (early November?) to get the better price. Or if you don't feel you want to push them, make it the absolute deadline in December. I feel people need to feel a push/feel a crunch on time to get them to move, so I would probably make it November. Truth be told, most people needed multiple reminders, and we had the most people book in the last 1-2 days!
I have a few guests that are not sure re fiances, so they were given an extension on RSVP (will have to book alone as missed travel agent deadlines) but we only opened this up to people who expressed interest but had concern. We only have 1 couple who spoke to us, so I have some extra stuff for them if they do end up coming, but it will probably be last minute. I wouldn't do this for A LOT of people because your resort needs numbers, your budget needs numbers, and you will need to order gifts, etc.
Hope that helps!
