A few months ago, we went to Hua Hin Thailand which is about 3 hours from Bangkok. It's known for being a "family friendly" destination in contrast to Pattaya which is a very hard party place lol. That's what they say at least, we've never been to Pattaya. :D
It's a very chill place.
The best for me was the beach not being deep. It doesn't go deep too fast but kinda downside is it's also too shallow lol. If you want to go swimming you'd have to go farther which I didn't like but that's fine since I don't wanna swim anyway. :D
The following pics were taken by 
The hotel we went to was nice although it made me kinda squeamish with the pool. The stairs from the balcony or something was wood and it touches the water and maybe just the tile color of the pool looks "dirty". I don't like pools that look cold you know? I like water that's warm. :D
There were also not much tourists/guests that time we visited. I think maybe 10 guests?
The roof deck of our room was also nice + it has a bath tub and shower. There's not much of a view since we're not high enough but still nice just having an option to be there for a quiet time without being inside.
We also visited the night market at around 9:30pm and it's so quiet. There were barely any tourists and they also close pretty early at 10pm. It was kinda weird feeling haha especially when the people we talked to in Bangkok said usually there are a lot of tourists that month. So we were
And of course, I wouldn't not take pics of street art. This one artist in particular is very recognizable and seen basically everywhere.
These are just a few shots of the art with the same style but there's literally plenty of them around. I'm glad the city is okay with it (or not?) and I can see their art scene is pretty vibrant with those. It makes the lonely-looking streets alive.
And lastly, their taxis look like this... I think they were also quite expensive haha and we just took a Grab car anyways. We only stayed a few days here and overall really it was just chill. We didn't even get to the caves and that area with the thief monkeys lol I guess we were too tired those days.
If you really want peace and quiet and to not interact with anyone this is a perfect place for you... that's if you want a beach but not go too far from Bangkok anyway. :D
