We have APs and have been to WDW several times in the past few years. We were at DHS a week ago Sunday with our three boys, and things have certainly changed. In the past, we've always arrived about 1/2 hour before rope drop, been near the front of the rope line and had fun with our speed walk to TSM. Now, it's hard to know when to arrive. When we arrived before 8am for our H&V ADR, guests were already lined up at the regular gates for a 9am opening. Not a few guests - lots of guests - more guests than we usually see when we arrive 1/2 hour early during peak season!
I knew about the fuzzy opening time, but was surprised to see the extent of the domino effect on our plan. Under the old system, we would have been walking out of H&V at rope drop and been on TSM standby. Under the new system, guests had been entering for quite some time and by 9am "opening" the line for TSM was already longer than we were willing to wait. So we grabbed FPs for TSM, which had an impact on our plans for the rest of the day.
Next time, we'll have a different strategy from the start. I think it will involve FPs for TSM from the beginning with no attempt to ride standby. We'll plan to stick around long enough so that we can pull FPs for RnR and use them after lunch. Easy to adjust - just different.
