Yes, that was my experience also- though not with
DReams unlimited- but I feel they are all similar.
If you are not paired with an agent and want a very specific trip/cabin on opening day - I think I would book it myself, and THEN transfer to a travel agent for some OB credit.
Honestly, I’m weighing this still.
The back and forth with the travel agent nearly cost me $100 last opening day- I would so prefer to do it all myself...
