Thailand is quickly becoming one of the most touristic countries in S.E. Asia. Visit it soon before the prices go up and the uniqueness goes down.
For a real thrill try a dive boat in Thailand!
I was lucky enough to get to spend 4 days on a Live-aboard dive boat. We launched from near Phuket. It was a great experience. If you love to scuba dive I highly recommend doing a live-aboard. You sleep, dive, eat, dive, eat, dive, eat, dive then sleep! We did 2 dives on the first and last day and 4 on the middle days. The food was top notch also, or maybe we were just really hungry! At the end of the trip they gave us a copy of a compilation video from our trip. Here it is on YouTube VDO Sawasdee Fahsai16
The food in Thailand is an experience in it's self! You find a wide variety of things offered to eat. If you love to eat at Thai Restaurants you know how delicious the food can be. I went in search of new dishes while I was there and found many not to my palate's liking. The Thai diet is not restricted to the same sources of protein as many western diets are. I found grasshoppers, crickets and silkworms all deep fried and sold as snacks. I tried a cricket, it tasted like a potato chip with legs. I am sure I did not see the entire selection of protein sources they use.
The hotel I stayed at in Udon Thani on my first visit to Thailand had a wonderful breakfast buffet. One of the dishes which was most memorable was a soup with congealed pork blood in it. Me being, Adventure Girl, had to try it. It was tasty, the cubes of pork blood reminded me of soft tofu.
One thing which will spoil you is the prices of the food at the small shops and stalls, (the prices in the touristic area restaurants are similar to the Thai restrains you are used to.) I was able to buy a serving of sticky rice in Pattaya in 2018 from a vendor in for about $0.25 USD. The same serving at a touristic restaurant there or most places in world is over $3.00 USD.
If you get the opportunity to go to Thailand make sure to get out of your comfort zone and try some foods you have not tried before. My general rule of thumb is: If other people eat it and don't get sick or die then I might as well try it. Who knows I might find a new favorite like I did in Cambodia!
