This is a professionally managed condo in a resort area and is exactly as generically "nice" as you'd expect it to be. Great Wi-Fi and fast internet. Much better than average TV setup in (20-ft vaulted ceiling!) living room (and TVs in all bedrooms). Four bikes; boogie boards; beach chairs; umbrella; beach wagon; snorkels; fins and much more beach equipment. Fully equipped kitchen. Ultra soft beds (too soft for us - c'est la vie). All in all, while we could quibble about specific aspects of the place, there is nothing worth mentioning -- it's a nice place with nothing objectively wrong or bad about it.
The Hilton Pool Pass is curious. The actual pools are only worth it if you have very small children -- they are a water park for people who've never been to a water park. But the salt water lagoon has surprisingly great snorkeling. We saw sea turtles, manta rays, many reef fish, needlefish, and even a few barracudas! There's a Dolphin Quest exhibit, too, if you're into captive dolphins performing.
The Hilton Beach Resort area feels like a theme park version of the "real" Hawaii. The restaurants are all tasty, but expensive and corporate. Good local restaurants are a 30 minute drive away (recommend a take-home poke bowl from a KTA Grocery and a mix plate from Ippy's in Waimea). Stay in Hilo if you want to immerse yourself in an authentic Hawaii experience, that'll be a little messy. Stay here if you want a curated generic tropical island experience where everything is "nice".
