I tried calling about 5 minutes before 9 this morning and got the recording that they were taking
DCL calls and everyone else call back later. So I followed the prompts and then got the try again message. Because it was nearly 9 AM, I went ahead and tried again; on the 3rd attempt, I got the hold music (whoop, whoop!) and a 37 minute wait time - but reality was the CM picked up the call in just 5 minutes. So we were able to get our cabins pointed/paid.
Sharing our experience so if anyone else is still trying to get a call in, try early tomorrow in case they have the lines open for DCL transactions. The CM told me they could only process the payment and DVC insurance things today - other requests, etc., would have to be a call back in August. Obviously we have plenty of time before sailing to handle any other business - I had just inquired because it's our first cruise with points in 11 years and I wanted to know the process for if we have things related to the sailing, do we call DVC or DCL.
I appreciate the tips, info, etc., from you all during this booking / payment process.
