Figured I would share my experience today with Opening day booking with a placeholder thru Costco...We have never tried opening day booking b4 thru Costco or Disney so all new to us
Called Costco today at Noon (Central Time)...waited 45 min...talked to 1st person who told me about there new procedure with placeholder (to call you back within 24 hrs) after you provide them some information about what you want...called it the GOOGLE Notes sheet...Then received call back around 230pm, So less then 2 HRS later...that person went over the notes put me on hold for about 5-10 min came back and said your all set....
So all went well for us, was worried I not would get the room I wanted but it was no issue...even scored the flag pole room
The one concern I would have if booking opening day platinum thru Costco with a placeholder if it was a popular cruise you would not get the room you wanted and maybe not get the cruise you wanted with the call back situation...
We decided if its a cruise we really want and could not risk this new delay with Costco that we would book directly on Disney Web Site to get what we wanted and transfer to Costco to get the gift card just suck up missing the 10% discount. Your results and solutions may vary...
