I have a Fire 7 and as I said Medallion Class and everything else works just fine on my Fire. Just out of curiosity, why do you have the concern about loading Google Play on your Fire? Medallion Class App is only available from either Apple or Google stores - Amazon doesn't have it (yet?), so in order to get Medallion Class on your fire, you would need to follow the steps outlined above. I suppose I will try my cell for those tasks on our next cruise.no way I'd want to read the Princess Patter on a cell though! Maybe I could read it in the cabin on TV? But I will miss holding the Patter in my hand while sipping my morning coffee on the balcony, listening to the water go buy. I understand and do support the cruise lines thoughts on limiting things like menus that we will hold, however. I'd prefer not using my Android cell as it's very small, hence my question. I suspect on our next cruise there will be very few paper forms, menus, Patter, etc available, so we will have to use some sort of electronics. I'd rather load only Fire apps on my tablet. However, I was asking if anyone had any luck downloading and using the Medallion app on a non-modified Fire. Thanks for posting the link for those wanting to try that workaround. Like I said, once I got it on my Fire, all of the features of the Medallion Class worked like a charm! I haven't noticed any other problems and it did open up availability to many more apps than just the Amazon store.
How to install the Google Play Store on an Amazon Fire tablet () Here is one link that gives instructions for downloading the Google Play Store.
The processor in the Fire is very slow so just don't be impatient. When I got up in the morning it was on the Fire. When I did it, the Google Play Store got on the Fire without a hitch but when I downloaded the Medallion Class App I thought it didn't work and went to bed. It's somewhat complex but if you follow the instructions step-by-step without deviation you can put the Google Play Store on the Fire, then search the Google Play Store for the Medallion Class App. You need to jump through a few hoops and install the Google Play Store on the Fire first. I have a Kindle Fire 7 and I was able to get the Medallion Class App loaded onto it and It worked fine on my last cruise on Regal in February 2020.
