After being sent the link to the website it took me over a year before I booked my first trip.......I've now done four and have three more booked. I still get nervous but I'm definitely glad I took that first step- I've seen places I never thought I would and there's plenty more to see.
A lot of people on here will say you get the bug.......I have.
I'm sure you have done the right thing...and if not at least you gave it a go.
Enjoy.
