Are people there more leading up to Halloween, or after? Like next year Halloween is on a Wednesday. So like I could maybe work out like a Sunday - Tuesday trip.
The bulk of HnH arrive early and leave Nov1 or 2nd. However many do come in a few days before Halloween and stay for a week, when the rsort is less crowded. Because 29th thru the 1st is generally jammed packed. So next year if you can swing it, your example planning would give you a big taste of HnH's party atmosphere
