Since we retired and not including "big health scare" years, DH and I have taken it in turns to choose a "Big Trip". We've been to some fabulous places inc Hawaii, Thailand, Canada, South Africa and the Cape Cod area of America. Next year is my choice and with the mortgage coming to an end, we have a budget of up to £12,000. Day to day eating and drinking would be paid separately. A lovely dilemma but I have been through brochures until my head spins and I end up considering pottering around France. Not a bad idea. I'm not asking anyone to choose for me but would love to hear from Gransnetters where you would like to go.
