The two plans demonstrate some changes that a trade show floor underwent between two years-2009 and 2010.
Overall, exhibition area was significantly expanded to accommodate more display stands although this expansion came at the expense of the meeting room and the conference hall, the latter of which houses fewer seats.
Focusing on the changes, refreshment and registration sides were switched place over the period while the entrences of the building, Main and Side, remained untouched. The stage which located inside of the Conference Hall also changed its directions while staying inside of the Conference Hall. The expansion of the balcony came at the expense of the lounge area.
Another noticeable feature of the map was place exchange between the Conference Hall and the Exhibition Area. Also the Meeting room was demolished and its room used for the expansion of the display stands in the Exhibition room while the stands of Conference room decreased.
