I understand completely. My first “ big trip” to Europe was supposed to be the only big trip so we set out to see as much as we could in four and a half months. It’s a long way from Australia. I saw so little of some places and loved some places so much I had to return- again and again. But each time I attempt to travel more slowly. I’m getting better at it. Instead of one or two nights in a place I now manage 3-7 nights. It much more enjoyable and a lot less tiring.
