PC has hotels that are often 20 years newer than in POP.
POP AI's are not being updated, and it only takes a few bad exp to make the whole area seem run down.
PC has far more marketing for a destination, not just by hotels, but as a destination.
PC has package deals often including air flights that make it cheaper than POP.
PC hotels all have websites and many are franchises to guarantee similar quality and standards.
The city of POP is nasty, noisy and polluted and has very little to offer other than the cable car, which is often not running.
The higher standards of the hotels in PC brings any unaffiliated restaurants up in quality.
So other than price, quality and location...
only thing with the cable car is that most of the Europeans who come to the DR have been in better cable cars than the Teleferrico.
