Never really got the urge to travel until we retired, now, with their encouragement, have been ski-ing (not the mountain type, Spending the Kid's Inheritance!) Started off with a round the world trip - Las Vegas, Fiji, Australia, New Zealand, coming back via Hong Kong and Singapore. It truly was the trip of a lifetime, will remember it always, and gives us so much more to talk about when meeting new people.
We could never afford another one of those, but in the past nine years we have visited Russia, India, Thailand, Vietnam, Cambodia, East Coast of Canada and also the Rockies trail Banff to Vancouver, Oregon, New Orleans, Memphis, Nashville, New York, coming back on the QEII. We have done the Orient Express to Venice, cruising back home via port in the Mediterranean, would just add a caveat that the old suspension made me rather queasy! 
I took a trip on my own to Kenya to meet the child I have been sponsoring, seeing the children in the Nairobi slums and the Masai huts in the Mara was something I could never have imagined, made me so angry at the extreme poverty, but also inspired at their happiness with what life has given them.
I truly believe you have to make the most of the short window between retiring and the onset of ill health. I never cease to be thankful that we have been given the opportunity to do this, we have one last trip to Kenya and Zanzibar coming up. I am not sure what else we will achieve, as DH is beginning to lost confidence in long trips, and also the funds are now getting low, but we are completely different people now to how we were 9 years ago.
Our grandchildren are our real focus, and when we have been away, have been able to talk to some of them on Skype and show them where we are. They enjoy us showing them a few photos and telling them what we have seen, which broadens their view of the world too!
Carpe Diem!.....
