If you are referring to wood used in the hotel, just hide between the chairs of the dining room (has a lot of dinner tables)
Coal blocks have more matching blocks in the map, though. :/ That's what I don't get about it being difficult. ;(
Once when I was a log block on the Town Square map. I couldn't find a spot to hide so I Went solid behind a log pillar in one of the houses. I won... somehow
Log. Definitely. There are only sideways logs in TownSquare, how the heck are you going to find a spot?? EDIT: Also, I forgot to add melon. I mean: there are -1 places to hide as a melon!
Somehow I have only seen 10 or so seekers go up the stairs in Villa in 3 games and none have checked the balcony even though I was visibly jumping up and down and some seekers did notice me. Very odd, they probably did not know the location of the stairwell.
