We were able to get an Ocean View Inn room for the 2nd-4th of July at the 7 mos window. We were able to book a non- Ocean View at the 7 mos window and waitlisted for the Ocean View, but it did eventually come through.
Don't hesitate to waitlist if you need to, we have had quite a bit of success on waitlisting for rooms. (of course, I do always have a back-up ressie in case it does not come through!)
Good Luck!
