Unlikely
The true "slow season" in St John is late September through October. Anytime school is out is a "busy season" in St John. Now that the new Bay Vista buildings are open, and possibly not sold out, you might have a chance with an internal StarOptions exchange. We've been owners there for 10 years in the 3 bedroom pool villas and only the first year or two were we able to even successfully shift our week within in our season. We've never been able to switch to a lower/summer week.
We are going Thanksgiving week this year, but only after being on the waiting list for 10 months and taking a Bay Vista unit rather than our owned/preferred Virgin Grand unit. We did have them note in the reservation that we own VG and would prefer one of those villas; our only hope is someone who's renting arrives and gets an unrefurbished unit and wants a "newer" unit.
