Has anyone used an agency in Ireland to plan group travel to the USA?

I want to plan large family trip to Orlando and NJ in March of 2010 and am looking for agency to arrange travel and try to keep price reasonable. Any suggestions?

Avoid guided tours. They are unnecessary and add unnecessary cost. Language should be no problem if you're from Ireland and you can walk into any restaurant in America and they will be happy you're ordering food. You can book plane tickets through orbitz.com or just look at the individual airline websites. Hotels? All the chains have websites where you can book yourself. IMHO, a visit to the US for the first time w/o NYC is like a visit to France w/o Paris. But it's up to you.
