We are planning our June trip and want to buy APs. We want to start with a four-day hopper (so we can get a MM) and then upgrade on our last day. Our passes will go from Wed-Sat. That Saturday, we want to enter with our hoppers and upgrade to APs. But that Saturday is also a Block Out day for APs. Would we have any problems? I would think as long as we did any park hopping we wanted while still using our hoppers and upgraded later in the day we should be fine, but I want to make sure. I mean what can they do? Not accept payment for my AP? Kick me out of the park as soon as I renew? Your thoughts?

) with the front desk of the resort, yes, you can upgrade. 
) which I believe is MM. We could wait until that day to upgrade, but I can't decide. It is hard for me to pass up the MM...I make sure we are always in line very early, we are often first at a turnstile. I can't imgaine walking in when the park is already full of MM guests and the lines....
Normally, I would just not go to DL on a MM day unless it was evening for shows.
