I image it will be the latter......I feel terrible for the servers.
We'll still use the DDP because for us, it's not about the value, it's about the ease of things. We normally tip extra out of pocket, so I'll just have to be sure to take more tipping cash on future trips.
We also tipped extra when we had a server go above and beyond for us. With that said, it is a big difference putting an extra $5-$10 out of pocket instead of 20% of a $150 bill.
The DDP was a great deal especially because the tip was included. The ease of use was also because the tip was included. We will be using the DDP on our Nov trip but that will be it for us. I just don't think it's worth it if we have to pay the tip. I also feel for the servers. In speaking with some in the past I know some didn't like the DDP because they had to wait up to 2 weeks for their tips. But now they will be getting stiffed an awful lot. We have AP's so I guess I will just get the DDE.
Thanks to the OP for this info!
