Congrats! My husband and I got married at EPM on 4/23/16 and it was the best time of my life!
I think the decision on whether or not to block the rooms really depends on your guests. If they're reliable, I would recommend blocking the rooms rather than using a travel agent. While you can get some great deals now through a travel agent, the rates go up and fluctuate a lot. If you block the rooms through the resort, you won't have to stress about that part of it.
Feel free to email me if you have any questions, or need recommendations on vendors. We used Alquimia Events for decor / furniture, Fine Art Wedding Studios for photography, and Samba Catamarans to rent a booze cruise for our rehearsal party. I would recommend all of them!
The only major regret I had was not booking an outside hair and makeup person. I personally, think I could have done a better job myself and they were extremely behind schedule.
