Verizon Mi-Fi jetpack. We have used it all over the US and even used it in Canada with 99% success. (If you have a good cell signal you have internet) Not cheap but you can use free wi-fi for non secure email and browsing when you are in a park that provides it and use the Verizon for banking, bill paying and shopping. You can connect up to 10 devices. I connect my Kindle and download free books from my home base public library using the Jetpack hotspot. When the grandkids come with us they connect their devices via the Jetpack.
