How many people have smart phones?
How many of those smartphones can be created into wi-fi hot spot?
How many FW folks are you using the MYdisneyexperience app on these phones?
I call my provider (sprint) add wireless internet hot spot service to my phone a few day before i leave and when I get home call and cancel. Cost $20 X 10/30 days. This way I can also set-up my devices with the correct wireless network. I also have unlimited data on my plan, you may want to double check this.
For the most part I then have wireless the whole trip, at rest stops, driving, and in my camper at the table. As the 4G mobile network is getting rolled out, my samsung phone is doing more and more heavy lifting by its self. The laptop is really just becoming my mobile storage for my camera......... and an extra TV with netflix and hulu+, combined $16 per month. I dropped cable over a year ago saving me $1000... now I use that to fund Disney Trips!!!
PM - if you have questions about internet over your phone. If you are unsure if your phone has this capability call you provider and ask.
