I literally just returned from Hualalai. They had a 4th of July fireworks bash that was attended by most of the hotel guests, many Hualalai residents and other locals who came for the buffet. That's the closest I've ever come to experience a "crowd" at Hualalai, and it was very manageable.

We went to the main pool to watch the fireworks and were able to find a number of open lounge chairs (we didn't do the buffet, which is where most people were still sitting).

Other than that, I've never experienced a non-guest event at the Hualalai, but from my personal experience at this resort where I'm a frequent guest and my observance of management practices, they would never host an event that would cause significant disruption or inconvenience to guests without a lot of advance notice about the event and its potential impact - last year's Mitsubishi golf tournament was one example.

The resort does host a number of weddings, and parts of the grounds might be reserved for the ceremony, reception, photography, etc., but those disruptions would be temporary.

I recall some flack over Pelosi's visit a couple years ago and "Ahnold's" demands for exclusive use of a pool even further back, and there was one online post at another site where a dinner guest was asked not to take sunset photos because an actress was seated nearby who wanted privacy (a request I would ignore as a hotel guest because I have every right to photograph the sunset and could care less about the actress) - but in summary, nothing in my own Hualalai experiences or online reading would leave me overly concerned about my visit being disrupted.

Four Seasons Maui - that's another matter, and based on my reading of various threads here at FT, I would never stay at that property....the whole place seems like one giant clusterf** and management apparently doles attention to the highest bidder or most stellar celebrity onsite while ignoring everyone else.
