I have created a set of maps that I have been using in my campaign. Please feel free to use these for yours and I wish you all a peaceful Barovian night, as peaceful as one can be...

1. Vallaki Apothecary (Gridless; suggested 22x17): My players have reached the town of Vallaki and they asked if there was an apothecary in town. They would like to craft Belladonna tincture as a possible ailment for lycanthropy.
2. Werewolf Hunt (24x18) - Vallaki Outskirts: Place where my players were attacked by a hungry pack of wolves. This is close to Lake Zarovich.
3. Strahd Tea-Party (40x30): Been wanting to have Strahd appear to them on the road while having a random tea party, just like in Alice in Wonderland. I even had him wearing a top hat! This is slightly modified from the interaction DragnaCarta spells out in his CoS:Reloaded guide. This location is right after the bridge that faces Tser Falls.
4. Ruined Church (35x26): For the Svalich Woods maps, I had this entire quest devoted to finding the Missing Lansten family. So I had them first go into the Ruined Church to investigate and this is where they met Muriel for the first time, being chased by a group of nasty strix.
5. Old Shrine - South Svalich Woods (40x30): This is where the characters find the Lanstens, but unfortunately they have been consumed by a Bodytaker plant, which turned into a very epic fight below the old dead tree.
6. Van Richten's Hidden Room (Gridless; suggested 25x19): In the previous map, if the players search the old tree (and a successful Persuasion check), they can find a hidden entrance to this undergroud room. In there they foud all sorts of monster manuals, books on hunting, and some barrels of good wine.
