Doing the math, that's between 11 and 15 rooms per floor. That
implies a central core (for elevators and utilities), which is going
to be difficult to penetrate with RF.

Both options suck. Bug me if you want details.
Most hotels have CATV wiring. That's what MoCA was designed to use.
A decent MoCA system is expensive. My guess(tm) is about $250 per
room, or perhaps $30,000 for everything. That's still cheap compared
to a service call every time someone complains about crappy WiFi
connections, which I expect to be chronic. There are MoCA adapters
with built in Wi-Fi. Because of the cost, the usual method is to have
the visitor rent the MoCA modem from the front desk, connect it
themselves, and return it when they check out.
I've done two of these so far. Ignoring my learning curve mistakes,
it went fairly well. Biggest problem was visitors who couldn't figure
out how to screw in an F connector. I kid you not. I had cross
threaded connections, broken connectors, and even coax shredded
probably with a pocket knife. Seriously consider push-on connectors.

Yes, it's called a "wireless LAN switch". The intelligence usually
found in the access points is concentrated in a box that looks and
works like an ethernet switch. The AP's run PoE and plug into the
switch. Some random hits:
Higher power at the access point end is a lousy idea and just creates
more interference. It creates an "alligator" (big mouth, small ears)
where the transmit range of the AP is much larger than its receive
range. Without a corresponding increase in laptop and PDA power,
cranking up the AP power is a wasted exercise.
