=X= (the shorthand for Celebrity, as the Greek letter Chi is the logo) expects you to download the Guest Booklet. We don't get them in the mail anymore. Congrats on using a computer. Baby steps. Hey, you made it here!
Magnets did not work on Equinox on the walls of our Sky Suite. That's after the Revolution refurb. Not sure about you're cabin. They work on the doors. You can get suctions hooks at Target that stick to the glass.
The =X= app is quite useful for checking daily activities and the menus of each dining venue. If you don't want to use it, there's still a paper planner (Celebrity Today) delivered to your room. If you want a tech-free cruise experience, you might try Oceania. No app. No "non-refundable" fare. But lots of fliers in the mail. LOTS.
