Everytime I've seen a really good "deal of the week" in our local paper, or everytime a friend has come up to me and said, "I saw this really great deal for such and such a place", it's always been for one of this company's deals. Gate 1 Travel always seems to have the sort of deals where you go hmm, WE could afford that... They do tours all over the globe, but the ones that have always interested me, are their European tours and cruises. Check them out, you'll see what I mean!
PS - I don't get any advertising money from them or special perks, I'm just passing along what I've seen and heard.
