The Quality Hotel in the west end of Grande Prairie should be included in that diagram. It's located on the service road just south of Richmond Ave (100 Ave) and west of 112 St in the north edge of the west side industrial area. That hotel is about 10 storeys tall and was called the Golden Inn when it went up.
Here's a (crappy!) pic of that hotel:
I'm glad to see that the Prairie Sunrise apartment tower's on there, though. Goes to show that 214 Place (the black office tower in GP's DT core) isn't the only highrise that GP has.
