Hi MzReborn - welcome to the forum!
I have an iPad 2 w/ Wi-Fi only and use the device (w/ a Bluetooth KB) when on the road - invariably stay @ places w/ Wi-Fi, either in the room and/or in the main buildings - this is usually a 'free' offering. Now if you want internet contact while in a vehicle or in a locale w/o Wi-Fi, then Gabriel's suggestions are a good consideration, i.e. using a 'cellular' connection to establish a Wi-Fi hotspot; the downside is the typical added expense - might be an extra charge on the cellular phone or w/ Mi-Fi, a monthly contract, although I believe there are 'pay as you go' options (in fact, I must look into the latter!) - good luck and let us know what you did!
