Visit half a dozen countries whenever you choose at no cost
Learn many interesting things about half a dozen countries, and others as well.
No hassle of getting pasports, buying air tickets, waiting in airports, money exchange or security hassles.
Take the trip on any day that you choose.
At absolutely no cost (since you have computer and internet access - but you do need ability to receive sound).
Visit my thread dealing with this issue on the "Retirement" forum.
Happy no-cost travelling, everyone.
P.S. Especially interesting to night-hawks.
