I've previously traveled with Contiki in Europe, and I found this trip to be completely different from that experience but for the better. We were in total a group of 11 so the group was A LOT smaller than other Contiki tours which I loved. We all got close so fast and got to share experiences like night diving with Manta Rays together and it was amazing. Fair warning, Hawaii is expensive but I found the Contiki tour price to be an absolute steal considering everything that's included in comparison to general prices of Hawaii. Not to mention our tour guide Dave was the man and made all of our experiences that much better. I'm so glad I got to share this experience with a great group of people- it really was a trip of a lifetime.
