It seems several of the resorts are trying to force you into using their "on site" vendors by charging you an fee if you try to bring an outside vendor.
We were married at the Majestic Colonial in Oct/2011. To use outside vendors they want to charge a $300 fee per vendor, and if the vendor is bringing an assistant, the assistant also needs a day pass ($100). So right off the bat you're paying an extra $400 to get your choice of photographer/videograpaher/DJ/etc. T
They do this because they take a a portion of the $$$ made by the on-site vendors or resort recommended vendors - the mini-monopoly they've created. To make sure they don't lose that $$$ by you bringing in someone else, they impose the "fee".
They are particularly sticky with vendors that are local to the DR/Punta Cana ... because those vendors are direct competition to their on-site vendors. There has been a lot of discussion about it on the Majestic Colonial Brides FB page. Not great news, but the way the game is being played, unfortunately.
