Mr Em is a great tour guide! he's very patient, friendly, and informative about the places. i learnt alot from him. the places are all incredible. hot spring was kinda meh, but its on the way to chiang rai so why not. the long neck village as well. but you can opt not to go in the village, you can kill time at the cafe on top the entrance. great coffee with a view! and cozy too! all the temples are soooo beautiful. we had a safe ride for the return trip so kudos to the driver mr man. its a longggg day so make sure you bring and use sunscreen and umbrella. it was insanely scorching, and then strong rains at the same day. the buffet place was really nice! lots of choices and its right next to the white temple. the journey back from red temple is about 4 hours, you'll be so tired so everyone just sleep in the van. you'll get a break at a petrol station to pee or buy things!
