Upgrading the costco 4 day hopper?

[happiestever]

Is it possible to upgrade to the so cal (not the select) annual pass after using the first 3 days of the costco hopper? Or do I have to get the deluxe or premiere?

you can only upgrade if you are paying a price difference, so if the Costco 4 day hopper is priced less than the So Cal AP you want then you will be fine, however, if the Costco 4 day hopper is more than the So Cal AP you will have to upgrade to the Deluxe.

That is what I thought. Thanks
