We have 8 tickets to purchase and we might park hope once or twice a trip. I am considering switching my 6 day park hopper to a 9 day base with the waterparks and more option.
I read on here a while back that if someone wanted to purchase extra base days instead of a PH, that they could just use one of the extra days to enter more than one park a day. I called 407wdisney and asked about this and they said that it's not possible.

The CM said that you can only go to 1 park per day with a base.
What I need to know is, has anyone actually used extra days on a base ticket to enter several parks in one day. If so, when was this?
Thank you so much!
