I had seen that thread, PrincessShmoo and read it with interest as I had just booked an OBB placeholder last month and had planned on booking on opening day w/DCL for Hawaii 2020 and then transfer to Costco Travel. I have NEVER used a TA. Not once. I have been booking travel for myself and family as well as for others for many years because I enjoy it. But being a longtime avid Costco member, I wanted to transfer my newly booked (booked on platinum release date) cruise to Costco, which I did. (feels REALLY weird to pull up my DCL rez and see the "talk to your TA" message. LOL) I SPECIFICALLY asked the guy I spoke w/at Costco Travel if they could still issue me the cash card since I had booked my placeholder w/DCL and was later transferring to them. He verified YES, that I would definitely still be getting the Costco cash card after I take my cruise. SO I have a looooong time to wait to make sure that comes to fruition!
I have to call them today with a quick question, so I'm going to ask whomever I get today as well. I'll post here what they say.
