Yes, Open Season rates still increases as expected but it's not as high as what was originally published back in December 2014.
In 2015, they were changing Open Season rates to the following which brought on the protest:
Studio $60- $290 (from $60 to $145)
One Bedroom $80 - $580 (from $80 to $290)
Two Bedroom $105 - $750 (from $105 to $375)
Three Bedroom $160 - $860 (from $160 to $430)
For example, what used to cost $80/night for a one bedroom can now cost you $299/night (in 2017 depending on location) if it's the only available one bedroom unit size to select from.
Here's what I've observed during my years of ownership. We started with a very simple flat rate based on unit size only. It has morphed into all sort of increases based on unit type (standard, plus, premium, etc), day of week (weekday vs weekend), season (platinum, etc) and now locations.
NOTE: Folks weren't happy with the earlier rate increases (see table below) but the 2015 rate hike simply pushed folks over the edge.
