We stayed in the Park Avenue room for 5 days, this was my first time staying on the Strip in Vegas.
First of all when I booked the room I asked for a (non-smoking) King bedroom for me and my GF, but when we got there they told me they only had 2double rooms left. I let the check-in guy know that I had booked a king bed almost 2 months ahead of time, and he actually got annoyed with me and went on a spiel about how they don't guarantee anything when I book. After I started getting annoyed myself he finally told us we could have the wheelchair accessible room, which had a King sized bed, and the only difference was it had railings in the bathtub. Fine.
Also, 2 nights in a row, around 6pm we had hotel staff walk right into our room without knocking. Even though the room was already clean. We went straight down to the front desk and he let us know that sometimes management comes to inspect the rooms to ensure they've been cleaning properly. Thankfully it never happened again after that.
Pros
Very Cheap to Stay in
Nice sized room, very clean and big
Great View
Very comfy beds
Roller coaster didn't bother us with noise
Good selection of fast/cheap food in the lobby
Fun but expensive piano bar in the lobby
Cons
They Don't Guarantee the Room you Book
Sometimes Rude and Disorganized Staff
Ancient TV, with bad reception
$15/day Resort fee, which gives you Internet and a coupon book.. Sounds like a scam.
