Make sure that you go to GUEST RELATIONS, be it at one of the parks or DTD.
I was there the last week of Feb. I went to Guest Relations to check on the plus' that I had left on a old pass.
While I was there thier was a family getting ther old passes checked again, because the CM at there resort had told them wrong (Yes, they were staying on property.). It seems the CMs at the resorts can not check the passes, so the little CM had just looked at the pass and and said that it had 4 days on it, wrote it on the pas and everything. But it was a 4 day park hopper, and they knew that they had used it on thier last trip.
So this family goes to the park and can't get in. Why? Because the pass had no more days on it. So, the next day they came to the Guest Relations office at DTD to double check the pass. They had told the Guest Relations CM the story that I just typed above. The GR CM checked the pass, and sure enough the pass had no more days on it.
She told the woman, that when it comes to checking the remaing days on the passes, you need to come to guest relations, see the CMs dresses in the Guest Relations outfits, to get the 100% correct info on the passes. Because they are the only ones who can tell you corrctly what is or isn't on the pass.
