Thanks to all for the info. I did call the hotel today. In house reservations is closed on weekends but the lady who answered the phone was able to tell me that ocean front rooms are floors 4-6 in the two beach-facing ends of the U that is the Kamehameha Tower -- as Rockyrat said and not too different from what writerguy's diagram shows. And as Rockyrat says the other tower is now MVC.
From a view perspective we would prefer the MVC location as we are not interested in the pool view and would rather have the more unobstructed and less busy view of the beach and ocean. But the MVC isn't an option.
We're trying to decide between our first stay here and staying at the nearby Hilton where we have stayed twice before. Pros and cons at both places. Now at least we know what ocean front looks like at both. Lots of other factors to consider. Maybe I'll set up a spreadsheet to compare.
Thanks again everyone.
