We did Celebrity's Infinity departing Honolulu April 18. We flew over to Honolulu 3 days early and saw Oahu on our own, then boarded the ship and cruised the islands. I'm not sure what we liked the most: the islands ..... or the ship!
After cruising the islands, the ship sailed 4-days back to Ensenada, Mexico. We were fortunate to have a cabin with a verandah and only had 1 day when it was really too cool to have the door open or to actually use the verandah.
We were bused from Ensenada up to San Diego and flew home from there. We liked this route rather than the reverse, which is sailing from Ensenada to the islands and departing from Honolulu back home.
We really enjoyed this cruise. WHile you don't get to really see everything on each of the islands, this cruise, like the Medit. cruises, gives you a chance to get a good overview.
We were able to see much of each of the islands because we rented a car and did not do shore excursions through the cruise line. Would strongly recommend doing this - doesn't take long to drive the "circle" around most of the islands.
I was on the same cruise as Pooh1Bear and also rented a car in each port and did the 3 days precruise in Honolulu. Just 2 cautions. In Maui I drove up to the vocano at 10,000 feet and it is a draining criss-cross drive. After decending, we then did the drive around the eastern coast of the island. The highway is very narrow and taxing to drive. The northern portion is a very good highway through the rainforest and the sights are amazing. The sourthern route has a terrible highway and is not worth the journey. Some rental car companies tell you not to drive this. There are no service stops and if you need a rest stop you will have to hold your breath. Drive the norther n route until you've seen enough and turn around and go back. There are some excursions that do the entire coast line.
In Honolulu I went to the Paradise Cove luau and was disappointed in it. Do the one in Maui if you want to do one. Enjoy your cruise.
