Australia is certainly full of beautiful landscapes. I've never been but my father lived there for a while and couldn't stop talking about it.
In early 2000's I went for a visit to Thailand my birthplace which was Bangkok. It was crazy fun but like you I left for Samui after 3 days. In 2019 my partner and I went to Bangkok and I assured him we wouldn't want to stay long. It was actually our preference and we couldn't get enough. We never made it to Koh Samui which was great back in the day.
There is nothing that fascinates me more than the Bangkok skyline.
I think Australia is my most favourite country I´ve ever visited. It´s so diverse and the nature absolutely fascinates me. Can´t wait to see all the animals again.
Yes, Bangkok is amazing and if it gets too much you need to leave. Last time we were there is already 6 years ago so I´m very excited. Nothing beats the skyline by night from a roof top bar.
