Sounds dreamy!! 2 days is totally doable.
I completely sympathize with the worrying DH. Mine won't "let" me (and I use that term not like I need permission, but he strongly prefers that I don't) go on an overnight tour alone. He is a pessimist who thinks of all the things that can go wrong. I tend to be a flighty optimist who sees the possibilities (and yet I'm a realist who knows dangers and when to flee).
I hope he gets OK with you going alone. Maybe if you checked in every X hours to let him know you're OK??
