I'm in Canada and most of our packages are for one week so that's fine with me!
The only thing that concerns me at Playacar is that it's a small resort and could get booked up before all my guests book... and I've heard the beach has a lot of randoms on it during the wedding ceremonies!
Oh yea. I don't see that bothering me. A friend of mine had a beach wedding here in the states and it was really random but extremely beautiful. It was on a public beach with plenty of sunbathers. Everyone was respectful and turned their chairs around to face the ceremony. It was a show for them and they clapped and whistled with us. I guess unless your resort has a private beach that's the only way around it. When I Stayed At RIU IN December The Beaches Were Packed So I'm NOTE Sure How They Will Set Up For Weddings
