In ports, look around for crew members. They will carry a laptop to their favorite hotspot to stay in touch with home. If you don't want to pay cruise ship prices, follow their example.
But, I also agree that we have become too dependent on staying in touch. Even business stuff can be put on hold for a week by leaving an automatic
"I'm out of the office until ...." message.
The only time we have used the internet was when we had a desperately dying pet and needed to give permission for treatment for neighbors who were taking care of her. Anything else gets put on hold. That is what vacation are for. And, we run a business from home too.
