First you need to narrow down the country then the resort. You may want to consider the Iberostar chain of resorts in Riviera Maya. There are 5 resorts on the same property from what I know and they have different price ranges. The Iberostar Paraiso Beach seems to be the cheapest. Essentially this might give your guests more pricing options while technically being on the same property. Something to consider.
Wow I am planning my 2016 wedding and have not even thought of this. Yikes!! So many different details to consider. Thanks for the reminder. Added to my to do list. The shoe options above are cute btw.
A lot of times people add attachments to their posts which you shouldn't be able to to download until you get to 150 posts. An error message pops up for most people. If you have access with under 150 posts, you my friend are lucky.
Try a search of invitations. I usually can't help commenting because there's some amazing stuff that people come up with. If you're a DIY bride it would help a ton. Goodluck
