Pre-Paying Gratuities with MTD

[smtwist]

Hi!

I saw something that said if you choose MTD you must pre-pay gratuities. Is this true? If so, how does that work?

While that is displayed during the booking process, it isn't required at this time (it used to be a while ago). 

I booked MTD almost exclusively and prepaid gratuity isn't required.  I usually choose to add prepaid gratuity but that is my choice, it isn't required.

On the cruises we've taken over the past two years, plus the ones we have booked, we have/had MTD on all of them and have NEVER had to pre-pay gratuities.
