Reading all the good reviews from here, I gave Oahu Airport Express a try on my recent trip to Honolulu (April 2010). Called two days prior to arrival; courteous gentleman "Dave" took the call and clearly explained the process of pick-up at airport. $30 up to 4 people in a van from HNL airport to Waikiki is a fair deal. Upon arrival at HNL, I called Dave and within 3 minutes he was outside waiting to pick me up. Also utilized their service going back to the airport on return. Van was clean. Driver "Dave" very professional and prompt. I would use this service again without hesitation. Kudos to Oahu Airport Express.
