Great place if you plan for North Shore activities. We got to see some big wave surfing and it turns out the snorkeling right by the hotel is pretty good even when the rest of island is shut down due to high surf. The hike on the NW side of the island to the bird sanctuary during afternoon / sunset is sublime.
The Island as a whole is rather crowded during holiday season and traffic / parking follows so don't arrange your day around traveling around the island if you can help it. We made that mistake and lost about a day as we could not do our intended activities due to too many tourists like us.
The Wifi is pretty fast but not latest generation. Probably for the best so you don't get sucked into doing work and only do web surfing / movies.
Gar also provided some snorkeling gear (3 pairs of flippers and one mask, 2 boogie boards). Unfortunately the best place to rent snorkeling gear at a reasonable price is snorkel bobs in Honolulu so make sure you take the into account.
