No. I am pretty sure that if you don't have the photopass tied to an AP, photos expire after 45 days. Once you activate a Memory Maker, it is good for 30 days. So unless the trips are no more than 75 days apart, one Memory Maker can't cover both of them.
Ah, we are APs.
Per the Photopass info page (
https://disneyworld.disney.go.com/en_CA/photopass-expiration-policy/)
"If you are a Disney Premier, Disney Platinum Plus, Disney Platinum, or Disney Gold Annual Passholder, all Photo Content associated with your Disney account that was captured at Walt Disney World Resort (and the
Disneyland Resort, if applicable)—while your qualifying Annual Pass was valid for admission to a Walt Disney World or Disneyland theme park—will expire
365 days after the Photo Content was captured.
All other Photo Content, as available—captured before or after the period that your qualifying Annual Passport was valid for admission to a Walt Disney World or Disneyland theme park—will expire
45 days from the date the Photo Content was captured.
If you have purchased the Disney PhotoPass downloads benefit for Annual Passes (“Annual Pass Downloads Benefit”), all Photo Content associated with your Disney account that were captured at Walt Disney World Resort—while your Annual Pass Downloads Benefit was valid—will expire 365 days after the Photo Content was captured.
All other Photo Content, as available—captured before or after the period that your Annual Pass Downloads Benefit was valid—will expire 45 days from the date the Photo Content was captured."
What is interesting is that I just looked at my photo gallery. We bought AP vouchers in the fall but did not activate them in park until the end of February. Photos we had from our runDisney races in October (when AP was not active) show an expiration date of one year later. Photos we took starting after we activated our passes in February show an expiration in mid-April. We do not have the Photopass add-on. Seems backwards from what is described above? But then we aren't operating on a Gold/Platinum/Premier/whatever system anymore either, so maybe that info is overdue for an update.
