I would do the upgrade to No Expire only if the ticket will cover two or more complete trips. It will be $225 (plus tax) to do the upgrade. If, for example, you do seven days this trip and plan on seven days your next trip, you will need (on the next trip) to buy a four day ticket which would be $243 without hopping.
And I agree with the comment that if you do water parks or DQ at all, if you do go to NE that you add the WPF&M option for $55 as the fun visits can still be used after all the major park entries are used.
