Theresa Odom at Expedia Cruise Ship Center did a great job for me on a land tour. Her office is located in a new building across the side street from Walmart on 466. Also, i made my own arrangements this year with Grand Circle Travel, which does not use travel agents, and enjoyed two marvelous trips back to back...if you plan to use them please pm me and i will give you my referral number which gets you $100 each off a trip and of course also helps me build up referras toward a free trip
They also do Overseas Adventure Travel for small groups and river cruise trips.
