This was not my first Contiki, so I knew of its reputation of having its fair share or partying, especially given the demographics. Nonetheless, I was taken back by the lack of respect travelers showed for the culture & religion of the countries traveled to given they are indeed more conservative Buddhist countries. Yes, we are adults, but the poor behavior went unaddressed by the trip manager and was offensive to the local citizens. I found myself embarrassed to be associated with Contiki on several occasions, including when female travelers posed nude on a mountain top directly in front of the trip manager and uncomfortable Buddhists shielding their eyes. The trip manager should have addressed cultural insensitivity numerous times and did not. That gives Contiki a bad reputation as well.
In addition, many of the stops seemed rushed and were check the box items, such as the Added Waterfall Optional and not allowing time to even get to the top level where rope swings are. At least find time for that if you’re already at the waterfall and paying extra.
All in all, I was a bit disappointed and embarrassed. Would definitely tell people to think considerably about what they want out of the experience and where they’re going. For more conservative countries I would suggest not to use Contiki.
