I'm with Oklahoma on this
I've travelled to some weird and wonderful places over the last 40+ years but New Zealand is the one that keeps beckoning me to return.
It really depends on what you want from a holiday, beaches, scenery, culture, exotic food. There is so much to choose from.
I love many parts of the USA and Canada is a beautiful country. Malaysia and Thailand are two countries easy to visit for first time travellers but still provide different experiences to holidays within Europe.
For my combined retirement/60th birthday I took a round the world trip with New Zealand being the main destination. I did stopovers in Singapore, Sydney, NZ, Hawaii and California. I had already visited Singapore a couple of times previously but always enjoy a couple of days there. Have re visited Australia and had been to the USA many times previously and since but I am saving up for a return visit to New Zealand where I hope to spend a couple of months.
The problem is for many people once you get started holidaying long haul you start reading travel reports and think I would like to go there and you make lists on where else you want to go, and the lists get longer and longer.
Let us know what you finally decide.
