I take my laptop EVERYWHERE. I am a child of the internet generation, and if I am without access to the internet for more than 48 hours, I cannot function.
An EXCELLENT solution to this problem is pre-paid internet service. Much like a pre-paid phone card, you buy time and you can use it anywhere. Sprint, AT&T, and Slingshot all offer this service, which can be purchased at your local 7-11.
In my experience, Sprint is the best pre-paid internet service. It is designed with travel in mind. You can program a location into the dial-up software, and then give it a name, so when you travel, you just pick that name from a menu. So, if you are in Orlando, just set it up for a 407 number, call it "Orlando" and then you never have to look up a number again...just pick "Orlando" from your list. I am probably making it sound much more complicated than it is.
After you buy the initial CD, you can purchase more time over the internet. I believe that the rate is $.06 / min.
Best of ALL, you don't have to sign up with AOL...I made that mistake in NOV and they harass you and won't let you cancel. I signed up in NOv. and they extended my trial until April, hoping that Ill forget and then they can charge me their $24 access fee.
HTH
