I get the same way a lot of times. I have a certain dress in my mind that I would like but when it comes to trying that certain dress on I think maybe it won't look right on me. Then I have to try to find one that do. I get disappointed like that too when something I had envisioned don't exactly go as planned.
So @pddcmc what have you got done so far in regards to planning your DW? resort is picked I see? did you lock down rates with an airline/travel agent? Have you sent out save the dates/invitations yet? Have you spoken with a coordinator on site?
