At 7 months, a GV is probably out of the question. There are only 5 of them at the resort and during busy times (Easter and spring break are busy times), they tend to go right at 11 months.
Actually at HH, it's easier to get a 2BR than a 1 BR and separate studio. There are only 21 each 1BRs and studios at the resort.
If you can do a 2BR, I'd call day-by-day right at 7 months.
This year the resort had an Easter brunch at the beach house; I'd love to hear how it was from anyone who went!
