Beautiful shots and great TR - my wife and I spent 5 nights at Le Moana last July/August.
We'd hoped to go to Thalasso but availability never opened up. On the flip side, being on the main island did make running to the local stores (for cheap bread, jam, fruit, beer, and rum!) much easier and saved us a bit of money; we were able to eat off-resort much easier, too.
How was the snorkeling at Thalasso? It was great at Le Moana - we heard it was better on our southern tip of the island.
BOB is definitely a great bucket list trip. Glad you guys enjoyed it, too!
