I got that same sales push too. I'm getting married at Sandals and am dealing with Amy the WC in Miami. Initially she tried to sell me on the Vision in White package with the full 3 hr reception even though I told her that we didn't want any of that. I finally just said I'd think about it and let the whole subject drop.
I read about a photography promo package being offered to 2010 brides if booked by a certain date. When I inquired about extending that promo to me, being that my wedding is only 2 days into 2011, I was swiftly denied without so much as an apology.
In sticking with the BB wedding, I asked about getting an arch/canopy/chuppa on the beach for the ceremony and was told it would cost $600 (for 15-20 minutes)!
Not huge deals in hindsight, but I was a bit perturbed at the time. After reading a lot on this board and the Facebook page, I've learned it's a little challenging to customize the wedding packages due to the Martha Stewart trademark but Sandals is beginning to offer more options. Since you still have 10+ months until your wedding, there's probably a good chance they will have even more options than what they have now.
Are you working with a TA? It seems like sometimes they can and do get information prior to it being released to the public. In fact, I think there is a flower catalog that won't be released on Sandals' website until September but some TA's who specialize in Sandals/Beaches Weddingmoons have already received it. Or if you prefer to handle things yourself, you can just keep checking in with the WC in Miami. Sooner or later she'll get the hint that you're not going to buy anything you don't want. Also, the WC's probably prioritize the weddings that are coming up sooner rather than focusing on us who are still months away. Not to say we're any less important but lots can change on their end in 6 months.
Good luck! If you're anything like me, you just want to get the details squared away. I've had to relax a bit over the past few months!!
