I am buying a ten day hopper with WPF&M and No Expire. What happens to the WPF&M entries when I use up all my major (theme) park days?
In effect you have two tickets with different privleges on one card. Since you have the NE option all the entitlements are good until they are used up. Even if you use up all your major park days, the WPF&M enries remain valid until used. (Note you do not have to use the days consecutively.)
You have ten days of access to the four major parks (AK, DHS, EC, MK), and may visit more than one major park on a single day without any extra charges. Without the Park Hopper option you can only go to one major park per day.
You have ten entries to the minor parks (BB, DQ, OT, TL, WWS). These may or may not be used on the same days as you go to the major parks. However, if you went to TL in the morning, Oak Trail Golf in the afternoon, and Disney Quest in the evening of one day you would have used three of the ten entries. (Note that leaving and returning to the same minor park on the same day does not use an extra entry.)
If you go to minor parks only on one day and do not go to a major park you do not use up one of your major park days.
If you were to go to a Water Park in the morning and then one of the major parks for the remainder of the day you would have used one minor park entry and one day of major park entry.
