Internet
La Cruz: WiFi = the WORST – Used my KVH IN THE MARINA. No 4G
Paradise Village: Pretty decent during the day. At night everyone is going crazy on Netflix so it slows down a bit. Cost is $25 for 2 weeks of unlimited 4mbps down and 2mbps up. We normally saw 1.5mbps.
Voice
La Cruz: Calls barely worked on 3G. Used the KVH for phone calls.
Paradise Village: Reasonable service on 4G
Airport and Airport Transport
PVR airport is a tourist airport. When I landed I walked through customs and went to what looked like the taxi stand. The person at the stand asked where I was going and then proceeded to try to sell me a timeshare. WTF?! I walked away.
The cost from PVR to La Cruz was 750 Pesos. This 30 minute ride cost 1/2 the 3.5 hour ride from Mantachén!
Other
Uber is available in the Mexican state of Jalisco (where Puerto Vallarta proper is at) but NOT in Nayarit (where La Cruz and Paradise Village are at). This results in expensive cab rides TO Puerto Vallarta. Once you are in Puerto Vallarta proper you can get Uber back.
Uber fares are generally 1/2 the cost of a cab. Most drivers speak english and are pretty savvy.
Your Uber driver will be nervous when taking you from Puerto Vallarta as it is not legal there and there have been reports of Uber drivers being surrounded and their cars being trashed.
