We have stayed twice recently at the Modern Honolulu. The rooms are spacious, nicely furnished and comfortable. The service is outstanding. The proximity to activities makes it convenient.
The wheelchair access is very good in room and around the hitel and despite the lift to the driveway the bell staff make themselves available in seconds to help with the lift.
Because of the way the building was built, the view of the ocean is usually obstructed on one side by skyscrapers so city view rooms have nearly the same view as ocean view (so keep your cash and go out to the pool).
In room dining is absolutely delish, prompt & courteous.
Overall the Modern Honolulu is top notch.
