Luckyfrog...........Glad you've had such good luck with hosts. Many of us, Not so much........
I recently had a GVR host contact me about a tourney offer.
He couldn't offer me Anything different than what the offer detailed.
When he asked me for my CC# to hold the room?
I said, "Well, if you need the same info, as if I booked it online myself, what exactly do I need you for?"
He paused, and seemed genuinely baffled. lol
I then told him, Thanks anyway, I can take care of it myself, good bye.
So, Luckyfrog, many of us prefer to SEE our offers beforehand,
and usually do just as well booking it ourselves!
