Jade Mountain is an amazing recommendation, also check out Ladera, the Almond resorts, and Jalouise Plantation.http://www.ladera.com/ http://www.jalousieplantation.com/?cmpid=ppc-goo_jal_brand http://www.jademountain.com/ http://www.almondresorts.com/the-resorts/ Jade Mountain and Ladera are definitely pricey, but you can always break up your trip and spend a few nights at one of those resorts and then the rest of your trip somewhere else that'll be easier on your budget. I'm so happy to see that you guys are looking elsewhere than Sandals. You can get so much more for your money elsewhere. Friends of ours spent more than we did to honeymoon at Sandals in St. Lucia than we did to honeymoon in Fiji. That's absolutely ridiculous! :-P
We were planning on staying at Jade Mountain and eventually decided against it because we heard from friends it was horrible. Their rooms all have the fourth walls that are open and our friends who stayed there constantly had bugs and birds flying in everywhere. That was def. not how we wanted to spend our HM. So def. keep that in mind if you choose Jade Mountain. For $12,000+ you could do way better.
We spent one week at Morgan Bay Beach Resort and one at Crystals - 2 very different experiences, neither one a Sandals-like place. Rather than try to recap each here, here's my tripadvisor account so you can see my reviews of both of those places, plus other stuff we did there, http://www.tripadvisor.com/members-reviews/SunKissedKate . I think you can email me through there too if you have any other questions!
