If I book back to back cruises separately (I.e., book one and then book the adjoining one later), do I need to contact Disney or do they automatically know it’s back to back and treat it as such? I’m booking through Costco if it makes a difference. I normally call because I’m using a placeholder but in this case both are blacked out from using a placeholder so I’m wondering if I can just book the second one online (if the VGT price drops… see my other post…). I booked the first one months ago.
