I'm having the same issues and I'm about 3 months away from my wedding. Though I have to say as it gets closer to your date they (Tiara and Yanna) will answer you more often, and much quicker.
Make sure to confirm and reconfirm all of your questions and their answers. This week I had questions about using our iPod instead of the DJ and instead of helping to answer my questions all Yanna did was kept answering me with "DJ $250 usd". So aggravating!
Read this forum, start to finish, it has really helped me to relax and take it easy with dealing with the resort, Yanna, and Tiara.
You need to contact Yanna and ask her what time the sun sets in the month that you are getting married and she will give her suggestions of when would be the best time to start your ceremony. I totally miscalculated my time line and her suggestion and advise works out better.
There was a post somewhere on here that hadpics of the different color linens that they have at DLR, I think they were Hunter Green, Fuchsia Pink, Pumpkin Orange, Red, Brown, and Turq. If you search I'm sure you will find the post.
Also from my understanding the "decorations" that are included in the package seems to be; For Ceremony; tulle hanging from the gazebo sides, a table with a flower arrangement inside the gazebo, and chairs with white covers. Not sure if the sashes are included for the chairs for the reception.
For the reception; All the decorations that seem to be included for the reception is 1 centerpiece for the sweetheart table, the white covers on chairs, and again, not really sure about the sashes. I have seen on some websites girls in Forums writing that the covers for chairs and the sashes were included, and others writing the opposite, I'm going to have to ask Yanna about this.
