I saw that there was an annual passholdder onboard credit available so I called iDCL to inquire and was told since I have a credit from booking onboard that I can't apply the credit. I ran a search on DIS Cruise Forum and didn't find anything pertaining to multiple credits. And given that there are often different answers depending on who you get at DCL I though I'd ask here for people experiences with this. Is it possible to get more than one shipboard credit applied? I'd understand only one DCL credit but I'd think the AP credit be WDW funded as a AP Perk. I have written to DCL Guest relations to ask also.
