Curse of Strahd maps

I am strongly considering purchasing the complete Curse of Strahd module for Roll20, and just want to check and make sure that all of the maps will automatically snap and fit perfectly into a grid (no extra work setting dimensions necessary). If not, I may just be better off downloading map images online and wrestling with fitting their dimensions to the grid. Thanks!

Everything should be set up the way you would want it.  Check your Private Messages, I sent you one.

Haven't played as DM but as a player - yep all the location maps are made to a grid; large world or overview maps are not. Tokens are already scaled to the correct sizes
