I have been doing a bit of research for a trip to Florida sometime in the next few months, but living in California, my wife thinks buying season passes to Disneyland would be better for us. Some family members are heading down this weekend, and she'd like to tag along. Problem is, this weekend is blacked out for Deluxe Pass use. I know that if I buy the passes at the gate on a blackout day, I can get in that day. But, both Saturday and Sunday are blacked out due to the holiday, and we'd like to go both days. My question is this: Can I buy 2 day park hopper passes for the weekend, and then upgrade them to Deluxe Annual Passes on the second day?
