Kalia 1BR+ units are oceanview, 1BR are not.
1BR Waikikian can see the ocean by hanging over the balcony, looking left. 1BR+ Waikikian can see the ocean. 1BRPrem Waikikian gets a really nice view of the ocean. 1BR Lagoon can see the ocean unless you have a tree in your way. 1BR+ Lagoon gets a good view of the ocean, either Diamond head side, or marina side.
Kalia lanai's are smaller than Waikikian, and much smaller than Lagoon.
Lagoon is closest to the ocean, but the marina side overlooks the new pool, which can be noisy.
Pacman is right with both Open Season rates and transportation. For $15 each return, Robert's of Hawaii is right outside of the the terminals, it's the people in the bright yellow shirts. Although they stop at all the hotels in Waikiki, HHV is usually within the first 3 stops, and your return trip doesn't often stop either.
