As Robert said.. you can use the milestone rules for this adventure only. BUT if you do use the milestone rules.. then you will actually be shorting your player's characters of some XP then.
Just like how the old Encounters PDFs shorted PCs of XP with unjustifiable XP caps?
I probably won't use the Milestone Rule for Death House (always used the hardcover in the past to get around the pointless XP cap rule), but won't be adjusting encounters to make up xp gaps either. Ravenloft is supposed to be a difficult place to deal with, so I have no intentions of making things easier for the party by giving them more XP. Plus, none of us have seen the finished CoS book yet, so it's unknown how much of an advantage there is to be gained by running Death House first instead of just starting from Chapter 1. Once I get CoS in my hands and give it a good read, I'll make my final decision regarding the use of Milestone vs standard XP.
Truthfully, the only reason I took the pro-Milestone position is because Kalani's original post tried to disseminate information (quoting the RoT ruling) that was contradictory to an AL-specific document created just for this adventure. I had to make sure that the correct information was being sent to the masses. Any time information is broadcast in an official capacity, it should be properly vetted to make sure that it is accurate and doesn't run contradictory to the official documents regarding that information.
