We went the week before Easter this year. It didn't seem overly crowded, the resort is small to begin with so even at capacity it's still quiet. I am not a HHI owner and this was our first visit. We booked a 2-bedroom and had to waitlist 1 night in the middle of the week, but it all worked out.
Two bedrooms are the most common room and popular room types if I remember right, but there are some studios. I suggest call first thing 7 months out. Best of luck!
