Hi David,
Yes, it's true Wakatobi is being heavily promoted in the US at dive shows.
No, they didn't succeed so much to degrade your experience!
I wouldn't mind if I was one of the participants in your group. Wow, with this trip you will make a combination of a short city stopover (at one of world's greatest cities) with the charms of Bali and the wonders of Wakatobi, which will leave you with incredible memories. Sounds really fantastic! You will have a marvellous time, I guarentee!
For myself, it's very rare I go twice to the same spot for a holiday. Now, that should count for something as well, doesn't it?
Please tell me all about your experiences once you're back!
Have fun!
