ticket upgrade question

I'm not sure if this if the correct forum for this question but here goes. The difference between a basic 10-day and a 10-day hopper is $45. If I buy the basic, can I upgrade it to a hopper for $45 later if the basic doesn't work for us? Thanks:mickey:

Yes, you can upgrade a ticket after you've used it, (as long as there are days left on it of course!)

No matter how many days are left, you will still pay $45 to add the park hopping feature.
