Mandoo Tour - full day

Has anyone taken the full day tour with Mandoo? It's an 8 hour tour and we are in pot 9 hours so I didn't think we should even try to take this tour. The ship (Celebrity Eclipse) has an 8 hour tour. We weren't sure if they used Mandoo or someone else.

We booked with Mandoo for a half day tour on December 1, 2014. I made it 100% clear that we only wanted Mandoo as our tour guide. He loaded us into our van and we ended up with his brother, who didn't give us a true Island Tour. His brother was silent for most of the day. :-( I had heard about him doing this with other people, so I can't think is reliable as a tour company.

We ended up taking the "Around the Isle of Spice" full day tour with the cruise ship (Celebrity). Although the bus was narrow (so seats for two were cramped) we loved the tour. Saw the nutmeg plantation, distillery, waterfalls, Grand Anse. It was a delightful day.
