My vote is don't bring it up. You offered in Disney, right? She said no, right? When she is ready, she'll let you know. It's pressure. Just my 2 cents. I'd do what Dia said worked for her - work on some simpler physical contact first - hand holding, cuddling or something - and let that sit a while. The bed is a big step. Start with baby steps.
I know you aren't needy. You've been detached for a long time. But if she isn't ready, she'll feel pressured anyhow. It should be about what she wants, I think.
