This is a great tour of Oahu. Do this early during your vacation to get to know the island. There were actually more stops than those listed. Our tour also stopped at a fresh fruit stand and a macadamia nut & coffee stand - both were wonderful and had delicious food for sale. Our tour included lunch at Fumi's Shrimp Stand; they also have chicken for those with shellfish allergies.
Bring a bathing suit if you plan on going in the water. The area is VERY rocky and you WILL slip off of the rocks if you're not careful, so wear sandals. It's worth it, however, as the water is very refreshing, There are changing rooms in the area, just be sure to keep an eye on the time!
We also visited a Japanese temple, a sightseeing location, and the Dole pavilion. All excellent parts of the tour. There's a lot more to do at Dole than you'll have time for, so consider coming back another day. You'll also pass by Kualoa Ranch (filming site for Jurassic Park and many other movies & TV shows) so consider doing that another day as well.
