We'll be in Honolulu on a Princess cruise ship. The last time we were docked by the Aloha Tower so I assume that is where we'll be again this time. It looks like the Iolani Palace would be within walking distance. My question is if it would be flat or uphill to the palace? I thought we'd go in the morning and take the guided tour and then stay for the free concert if it isn't raining. If it is uphill it looks like we could take the bus. What would you suggest? Also....do you think it would be worthwhile to see the gardens at Queen Emma's summer palace? We wouldn't take the tour of the palace but just walk around the gardens if it would be worth the trip.
