This is good news. I'm excited.
I read on the Toonzone forums that the episodes are presented in chronological order, and somebody said something that I hadn't known until now: The entire series was produced in one production season, yet was split into four seperate broadcast seasons. That's interesting to know. That explains why some of the characters featured in the opening only appear in one or two episodes in the first season, and why the first season only has two episodes involving the hotel (plus one additional episode with Mr. Thickley and one additional episode with Constance). That is odd, since the hotel was supposed to be one of three main settings and the show had the format of two short episodes per half-hour (to be fair the first two hotel episodes both lasted the full half-hour). I recall seeing a full episode guide and it seems like the hotel episodes were spread out far apart at first.
Considering they were all made in one production run it's weird that the show is advertised as "Season one, part 1" (or volume 1, or whatever). I think it could have just been called "Volume 1" (makes me wonder if all sets, if we end up getting the whole series, would be labled "Season 1 part X").
