Hi Kate,
Yes, most of our guests are coming from the same gateway which helps the pricing to be consistent (Toronto is surprisingly more!). Thanks for letting me know about your photographer, I'm sure you will get amazing photos. With a location like a tropical beach you can't really go wrong.
As for dealing with our travel agent, it's been a piece of cake. I sent out email invites to our guests that had the link to the Now resort and the travel agents number and email and they book directly through her, then she gives us an update whenever a new guest puts a deposit down. There was no cost to us to use her. Most don't ask for money unless they are doing wedding planning. We also created a website for free on my wedding.com and I found it super easy to use and customize.
We have children and teens so we didn't even look at adult only but I have heard that secrets is really beautiful.
We are totally being those people and doing pink haha! I love your blue and lime idea but for us the guys are wearing grey and I love the contrast of a raspberry/fuchsia with the water and greenery. What about you, Melissa?
