When I spoke to the agent, I only had one days worth of ticket in my account. I'll be loading some passes we bought 10 years ago soon. I asked what happens does she need to link them? She asked if we planned to be back in the next 120 days. We said probably not and so she made the das from the earliest day we might be in the parks to the latest day.No, you should be good. I've only heard of 1 person who had DAS expire before the end of their visit, but they didn't have any other park days so it didn't matter. Everybody else has had DAS valid through the end of their visit.
