Yes, I've always got some responses back, could possibly be that ship is full???
Not sure, but there must be some reason no travel agents have gotten back to you, just be patient, you never know, good luck.
I used the Bargain Finder and was very specific in my request. I even listed the lines I did NOT want to cruise with. So what did I get? You guessed it, quotes for the lines I had specifically said no to.
None of the offers could top what I got from my own TA.
Guess the bottom line is pick the right time, the right ship and shop around for a good TA.
