Saturdays grayed out? - Selecting FastPasses from offsite hotel

Hi, is this a normal thing? First time I’ve booked FastPasses when staying at an offsite hotel. I logged in to select FP for November 3 and all the Saturdays for the next month are grayed out and I can’t select one. All other days in October work fine and are available. Is this a new “feature” for non-Disney resort guests?

What type of tickets do you have?

1-day non-Magic Kingdom, for 3 of us.

What season? Are the Saturdays a different season/tier?

I thought the seasons were just for the Magic Kingdom tickets? that might be where I’m having trouble…

That was it!! Thank you PrincipalTinker! You guys are the best. :smiling_face_with_three_hearts:
