I love how many GBP brides there are right now!!
The pricing is very confusing for the poolside reception, which stinks. Basically, the dinners include an hour (maybe two of drinks) but there is a 50 person minimum. I had the Grill option which is a 35 person minimum but they told me I couldn't have it for my wedding because it was plastic silverware. Honestly, I didn't care! I wanted my reception outside and I couldn't very well magically come up with 15 extra people! So after so pleeding I got the grill option with 35 people (I actually only had 32 people, but I paid for 35). Turns out, I got fancy china and silverware and the full service bar anyways! So if you really want your reception (dinner included) out by the pool, as about that option.
Someone asked about a veil. I had one. I tried it on the day before the wedding. I did not wear it. It was FAR too windy at the Hammock location and it would have been wrapped around my head. This doesn't happen every day, obviously, and if you're willing to stand on the right side and your FI stand on the left side it might not be as bad.
Natty, if you stay at the Akumal side, your wedding has to be at the Akumal side, which with any sizeable group I'm pretty sure has to be the hammock location.
