I revisited this rink last weekend and it was pretty much the same. The ladies room needed a good cleaning, but there was a huge hockey event going on here and at another rink in the area, so they were probably understaffed.
One note: the casino allows smoking, so the entryway reeks. The rink, not so much, thanks to the ventilation system.
I observed a LTS session on a Saturday. Most of the instructors were high school/college age and the classes appeared to be mixed levels. In one corner, there were four students, all working on different elements. Maybe registrations were low and they had to combine classes. (Better than not offering Basic 6 due to low enrollment, imo.)
