It is usually hard to get a GV unless you are somewhat flexible with dates. At least you have a back-up plan. Call on day one of when you could day by day reservations at 7 months and ask how it looks for the rest of the time you are interested in the GV. Call now and see how this June looks. I realize it's only a few months away but it may give you an idea of what next year will be like. Good luck.
