Best advice for a great honeymoon? Go for two weeks, spend the first four days somewhere utterly spoiling and pampering and ridiculous, the kind of hotel you would never ever stay in if it wasn't your honeymoon. Then pack your bags and move on to somewhere that gives you a little adventure of some kind, scuba diving, safari, rock climbing, horseback riding, whitewater rafting, whatever floats your boats as a couple, then for the last week find another fabulous hotel, not quite as swanky as the other one but perhaps with a cottage in the grounds so you can just be the two of you and enjoy the privacy!

Here are my choices:
Paris
Mykonos
Prague
Southern France (rent a villa in a pretty little village)
Tuscany (especially Lucca)
Barcelona
Buenos Aires
Salt Spring Island in British Columbia
Lake Louise, Alberta (if you love the outdoors)
I'm not into the dime-a-dozen beach resort thing, but if you are there are literally thousands to choose from and they're all going to be pretty much the same.
