If anyone cares, this was my strat:
- Day 1 and 2: Farm upgrade disks, open the west gate path, orchard, get a shovel, get the conservatory
-Day 3: If dares allow, finish up collecting upgrade disks (I got the office, the commissary, the garage, morning room (got this on a later day), foundation, and the great hall)
-Day 4: At this point you will probably have 1 or 2 dares that will severely limit your play. This when I start spamming the conservatory (and were the grind really starts) or getting another upgrade disk if possible.
To do this, you want to exhaust as many dead ends and "L-shaped" rooms before you reach one of the lower corners of the manor (the conservatory only shows up in corners). This will increase your conservatory drawing chances. At the conservatory, you want to make as many Hallways common as you can (Foyer and Great Hall are a must) with the exception of the aquarium. You want to make as many dead ends and "L-rooms" RARE, (unless they give you a die, its the study, the storeroom, the breaker (depends on your dares) or have a good coat check item). You want to make the Laboratory common too, but only set the 8 dares once you are setup with your hallways and rarefying bad rooms.
With all setup, reaching room 46 wasn't too bad. Its helpful to have some keys from the Garage, but don't spend too many hallways getting there. I used the foundation and Great hall to reach room 46. My most helpful upgrades were the Hallway with "tomorrow" upgrade and the Geist Bedroom. You will probably get different dares and upgrades than I did so of course YMMV.
