My understanding also. We have booked the Gold plan and it had to be done through WDTC (they told us any type of DreamMaker pkg had to be booked through WDTC not CRO).
This is too confusing. I just booked a silver package and WDTC transferred me to CRO to make the res. I double checked that I was speaking with CRO after being switched over and she said yes.
