Remember, there is a difference between Prime Pantry and
Amazon Prime Now.
Pantry does not have fresh food, has a $6.99 delivery fee from Amazon and goes to the front desk which may incur a $5 per package delivery fee. Also, delivery takes a few days
Prime Now has fresh food - lunch meat, fruits and vegetables, milk etc. It has a $20 minimum but no delivery fee. You can get delivery same day within two hours or choose a more convenient delivery window. Groceries are packed in insulated bags with cold packs and go to bell services where they have a fridge.
Some guests have reported bell services delivering to room while others have gone down to get them.
Looks like no $5 resort fee for Prime Now.
I cannot get to Prime Now from my Amazon account but can find it on a PC through Google and have the app on my phone. Same login and password as my Amazon
