DDP and Gratuities

[bostomco]

Last time DW and me had the DDP gratuities were included, which was awesome! But this time around I noted the gratuities are not included. So here's my question: Do I need to carry cash around with me to every TS meal to tip or can I put my tip on my keys to the world? :confused:

You can charge the tips to your room. :)
