I'm going to be in Tokyo, Kyoto and maybe other places. I have an iPhone 5s and my wife has an Android device and we have a few iPads. I also need to make sure I can use my MAcbook.

We'll be staying in pensions, ryrosan a few days, maybe some bigger hotels but probably smaller places.

Want to use Maps and train apps and so forth.

I'm wondering if I should get a mifi device, or what. Thanks for any recommendations.
