We just returned from a week at The Imperial of Waikiki...great weather, great food...just the best! Although we didn't have a car, I walked by the Hale Koa parking office to ask about parking for the general public. Anyone can park there for $12.00/day with a 3 day minimum. If you are not familiar with this parking facility, it is located across the street from the new Trump Tower and very convenient to The Imperial. This won't help the people who stay at Wyndham because of their mandatory $25.00 parking fee, but could be helpful to Imperial guests. The parking office is in the parking structure off Kalia Rd across from the Hale Koa Hotel.
