Question about wifi rental
You may not need it in WiFi. I found that there were many cafes, hotels and restaurants that offerred WiFi free. Of course, that's not the safest method. I'm hoping someone else can address renting a hotspot. Frankly, I use T-Mobile for my phone and it gives me hotspots free most everywhere in the world. Sometimes the connectivity isn't great, but I appreciate the lack of roaming fees.
