MDE app vs browser


So my husband has a smart phone but I made a voluntary return to a flip phone.... yes a flip phone.... a couple years ago. I'm planning on digging up an old iPhone to carry with me in the parks and use when my husband is off playing golf. I know the Lines app will work just fine, but I'm pretty sure the IOS on the old iPhone will be too outdated to download the MDE app. So, my question:

  1. Has anyone used the MDE website in a phone's browser and found it fairly easy or difficult to use?
  2. Obviously I'm most concerned about my ability to book fast passes. . . .so can anyone comment on that particular capability?

The alternative is for my husband and I to switch phones while he is off playing golf and I stay in the parks. Just looking at an option that doesn't involve me commandeering his iphone.


The only downside to that is the Wifi in the parks is, well ... suckage. I had to switch off Wifi many times and use my cell data to get a connection.
