Robin,
I don't know your TA, but I can highly recommend the guy who posted just before me- DavidO. His bookings have been flawless, and he always sends a copy of your itinerary with everything spelled out-including the upgrades or potential upgrades. He's a Virtuoso agent, but also books FHR (as I'm an Amex Plat holder) and LHW bookings. If there's an issue with a property, he's on the front line trying to resolve it.
No, I'm not getting any kickbacks from David- just good service!!
