WOW! Glad to know you had a great time on holidays! Cameron Highlands is one place I wish to visit, but never got the chance to go yet. My family members have been there around 10 yrs ago, but that time I was in the US as an AFS exchange student, so I missed it! My family really loved that place, they came back & told me how nice climate, beautiful landscape it was. Just one dissapoint thing was that they were there for only 2 days 1 night, spent almost 10 hrs also on the bus but being up there just for one night, that simply not enough. They were travelling with their friends as a tour group, so time plan were arranged by tour guide. Their trip were made of travel by train from BKK, after Cameron, they went to Kuala Lumpur for a sight seeing.
I also can imagine what you've experience about the traffic & crowded holidays, we've experienced the same in Chiang Mai, too, I was thinking
where are these people from....so so many tourists, seriously. I'm living with those heavy trafic everyday here, too.
Bangkok should be famous & champion for her super trafic jam, that should be added to travel guide book!!
