Thank you everyone.

We've researched a bit more and although BVIs seem to look more "yachty" the extra £1000 (based on £200 each for the Liat flight) could pay our food etc for the 10 ~ 14 days. As it's going to be an expensive holiday every penny counts.

We're not that fussed about night life as we're quite a quiet family and are thinking maybe the BVIs will be too busy, so maybe Antigua would suit us?

Our daughter's a bit wary of snorkeling off the boat so would prefer to walk from the beach - would the Antigua beaches be better for these, or elsewhere?

Thanks again
Ju
