Only semi-retired, in 2016, we visited: Cost Rica, Spain, Andorra, Italy, San Marino, China, St. Martin/St. Maarten, Anguilla, Belize, Honduras, Mexico.
In 2017, already visited China, will be in France (Paris) and Morocco (Marrakesh) in March, and in Austria, Hungary, Slovakia, and Greece in May. We have not planned the trips for the 2nd half of the year yet. Looks like we will visit 10 countries every year.
