Pam and others, thank you so much for caring. It's really nice of you.

Nah, I'm one of those type personalities (is it A or B or a combo or am I just a strange C) that naturally worry, hubby too, he puts his faith in me by allowing me to arrange everything knowing I'll really work at it.just normal for us.

Very little could ruin my trip (except for health issues or major disasters).

I don't see this the same as land/air travel at all, with the normal land/air, I can always change hotels, eat at different restos and fly home whenever I want to basically. Since this is the first one, I feel like I'm giving up some form of control and that's what got me nervous.

What I don't have is high expectations so I doubt very little could ruin my trip. Nerves, standard issue for me.
Again thank you all for caring.
