Don't look now....I just did...
I was looking at and modifying a couple reservation for my trips in November and December and have verified that the rooms at POP have gone up by about $15-$30 per night on a standard room !!
I had posted last year when the 2019 rates were released that the room rates at POP had only gone up by a dollar..I booked these rooms shortly after that. The good news is I was able to add on a few days here and there at the same rate

So the Skyliner has done what a lot of us thought would happen....$$$
Of course there might be a discount for the fall but I'm guessing not.
edit: a couple of the nights stayed the same over a 10 day stay.
