Hi there,
Roatan is my first option for my DW, I'm just hoping Sunwing starts offering tours earlier in the season, as I'd like to go in September 2011.
I have been to Roatan before. My FI and I rented a private vacation home in West Bay Beach and it was amazing.
Not sure if you're looking for an all-inclusive, but Infinity Bay is no longer part of Sunwing's all-inclusive packages (I heard this just a couple of weeks ago).
Here's a link to some other Roatan resorts that you might find helpful: Henry Morgan Resorts
