So assuming WDW does adopt a version of Disney Premier Access... much will turn on implementation.
But we can start to draw some reasonable inferences and conclusions on its likely effects, likely winners and losers.
So some random likely points and commentary:
- No more need to plan 60/30 days in advance: This is a big pro, IMO. You'll be able to ride every E-ticket attraction without the need to book a FP 60+ days in advance. Depending on the park pass system, you may be able to truly make your plans spontaneously.
- Physical standby lines will be much shorter. I assume the "Standby Pass" limits the length of the physical queue. The physical queue still exists, but "standby pass" gets activated when the line exceeds 30 minutes, or an hour, or whatever. So standing in 90-120 minute lines may be a thing of the past.
- Without tons of pre-planning, regardless of whether you are on-site or off-site, regardless of whether deluxe or value, everyone will have the option to skip the line on the major E-ticket rides. It will simply be a question of whether it is worth the $$$. The pricing is not outrageous at $10 to $20 per ride, or so. Yes, that would become super expensive if you wanted to purchase 10 per day for a party of 4. But every guest can decide whether it's worth the price, whether to buy none, 1, or however many.
-Morning arriving guests should be able to guarantee themselves access to a minimum of 1 E-ticket attraction per day, for "free" and without a long line. And it will be any attraction they want. As things stand now, it's very possible that even booking at 60-62 days, you can't get a free FOP fastpass, for example. Under the new system, any guest arriving around rope drop should be able to get a "standby pass." While not the same as a FP, it will guarantee you the chance to ride FOP with a reasonable line -- 30 or 60 minutes, or however they set it, instead of 2+ hours. And if that isn't good enough, you'd have the option of buying DPA.
- There will be increased demand for popular attractions, because you no longer have the disincentive of a long line. If you arrived at DHS at 9:30 am and see a 2-hour line at Slinky Dog, many people will decide it's just not worth the line and will skip it. But if the physical line is only 30 minutes -- More guests may be fine waiting in a 4-hour virtual line, if the physical line is only 30 minutes. This increased demand could lead to "Standby Pass" lines filling up pretty quickly..... meaning...
- The big negative, late arriving guests may find themselves blocked from "Standby Pass" at popular attractions. All the standby passes could disappear quickly. Like in the old days of paper FP -- Some rides would have paper FPs still available till late in the day. But for Toy Story Mania, all the paper FPs would be gone within 20 minutes of park opening.
So the big winners potentially under this system: Those arriving to the park early and those willing to pay extra for DPA
The losers: Those who arrived to the park later and relied upon pre-booked "free" FP to E-ticket attractions.
Guests who mostly/entirely rely on the "free" standby system will likely spend less time in physical lines (which was Disney's unrealized goal with FP+), but will lose Front-of-line privileges at any ride. Instead of 1-2 E-ticket rides per day with virtually 0 physical wait, it will be all attractions with under a 30-60 minute physical wait. It should strike a better overall balance of wait times, with the downside that guests may become entirely excluded from some attractions on some days. Currently, you can get your FP for Slinky Dog, and still decide it's worthwhile to wait in a 60+ minute line for Smuggler's Run, another 60+ minutes for Runaway Train, and another 60+ minutes for TOT. Under the DPA system, you might grab your Standby Pass for Slinky, but then get completely blocked from the other "tier 1" attractions.
