Activity for A

So my 1st option was the Don CeSar Beach front hotel in StPetersburg Fl, but they are way over my budget I would have to cut my guest list dramatically. And my option #2 is already booked!! I want to scream! I could change my dates but I really don't...

My FH just popped the question 4 days ago and I've been obsessing over Wedding plans. My question is, is it way too soon to start? We are having a 15 month engagement. How soon can I propose to my bridesmaids?
