If you want to avoid tourists befuzzled then go off-season. My wife and I travel around Europe, the Med and north Africa during the winter months when cities and resorts are much quieter. Airports are quiet, planes are less than half full, places of interest are quiet, hire cars are cheap and we are often the only customers in restaurants and on beaches. The weather is almost always good too. We always seem to have sunny weather and the temperature is usually a comfortable 70 degrees +.
We always stay at home during the summer months and public holiday time. That's when everyone else is packing the airports, sweltering in the heat, jamming the beaches - and paying twice the usual price for everything from hotels to meals. But if you like the scorching heat, prices and crush then go to the popular destinations in the summer season.
You can avoid the crowds and travel quite cheaply by planning your trips. We do travel further afield sometimes, although we don't like too many long flights. It will be the same in most places you choose. Plan to go when others are not there but if you want the heat, pump clubs and bars then you'll have to pay for it and join the crowds.
As jno and vehelpfulguy say, it depends entirely what you are looking for. I also suspect you won't be going too far but I really hope you do. There's a great big world out there to see. None of us get out of this game of life alive and too many people spend their life locked into a five day week and a mortgage. By the time they retire its too late for most of them to get up at 6 and hike all day in the mountains. We see them tottering along the prom in Portugal or Malta with their shorts, overcoats and walking sticks!
Go for it and enjoy that world while you can. The day will eventually come when you won't be able to. You'll be too old, too sick or too dead.
