Coffee Drinkers Please Help!

[Kathleen McDowell]

Hello. I own and manage a number 3 bedroom vacation rentals, hosting 6 guests on average.  I don't drink coffee so I struggle to know exactly what guests would prefer.  I have read that the choice of flavors of K cups may be appealing, but am not aware of which tastes better- Keurig or drip. Help me decide on the following and any considerations I am missing. I am not concerned about price, but more focused on 5 star customer experience.  Thanks for your help.

A. Drip Coffee Maker (this is what I have now)

B Keurig Coffee Maker (this is what I have in my small 1 bedroom ABNBs)

3. Duo Keurig that offers both Keurig and Drip
