It definitely got breezy at night but still very comfortable. I think between 6-10pm it will still be very pleasant, even off shore.
We used these for our invites (hopefully the link shows up - if not, we used weddingpaperdivas.com and the name of the invites were sea stars): http://www.weddingpa..._sea_stars.html. And we used the picture in my avatar as our save the date!
We bought our tickets about 5 months in advance, in early November. I think most of our guests started booking after the new year, so within 4 months. We kept an eye on air fares throughout - they did not seem to go down as it got closer. In fact, when we first started planning after we got engaged, around September, airfare was even cheaper then. I would recommend guests booking as soon as they know they want to go.
Here are some pics that show Bar Higuey from different angles:

Hope those help!
