Got it Mark. Didn't get that from the initial post that it was in fact a solo trip you were desiring.
I think it's a great idea. Also shows you know your relationship well enough to not ask for her companionship. Think it's pretty generous of you to offer up a separate trip. Just don't get why some women have to be so sassy about it. You can taste the jealousy in her reaction. With all due respect my friend. Good luck.
