My husband, daughter and I went to WDW last year on 7-day PHP (plus). His pass and her pass have 3 days left; mine has 4 days left (had to go back home for one day for a funeral). We want to go again in October and carry my mom. We need four days per person. If we purchase a 6-day PHP for my mom, can we use one pass to admit two people in one day? I mean, effectively using two days in one, not trying to sneak in w/o paying somehow. Or will we just need to buy Mom a four-day pass and then two single-day tickets for DH and DD, which will limit our park-hopping capability for one day?
