Let's kick this search off with a completely off-the-wall-no-way-I-could-ever-afford-it choice. Blackberry Farms!
Absolutely gorgeous but outrageously expensive. I once looked into getting a room there for a romantic weekend for The Boy and I but it was over $800 a night and it's only gone up. Our wedding photographer, Julie Roberts, told us that she had found out that it costs $68,000 just to rent the lodge out for the weekend. That doesn't include anything but the lodging - flowers, catering, activities - everything else is more money.
Sigh. Maybe next time I get married. :-D
