After five trips to Hualalai, we have only rarely seen this and when we have it has not been any imposition. A couple of examples come to mind.
1. We have seen private events on the lawn around Beach Tree, towards the main house. Appeared to be cocktails, impact was substantially zero.

2. Resident's Club bar and grill gets rented out. We didnt plan on going there, so didnt care. They did spread sand across sidewalk, but again, not really a big deal.

Most of these events are similar to managers reception, which is worth stopping by, Wednesday nights usually. Hualalai has enough room this is almost never a problem. The only time of the year that is is somewhat difficult is festive season when the resort gets filled with a lot of folks from the homes at Hualalai and their families.
