The only reason I enjoyed this trip was the people who were in my group, my trail leader was lovely and she chose and booked great accommodation, and the countries themselves were incredible. Our leader only had online training and Frontier had not told her the process at all, it was not clear what trips/travel and transfer was included (and a lot was restricted). Breakfast and lunch (which was included) HAD to be incredibly basic, very cheap local food eaten together at the same time. However this didn't take into account any other circumstances such as illness, group size, availability, price fluctuations etc. Our budget was tiny for the whole trip and if we didn't use it all on a meal, we never saw the leftover money.
There was rules with drinking and you weren't allowed much personal freedom - it felt like a school trip really. The safety regulations were ridiculous: not being allowed to slide down a slide at a waterfall, go on a banana boat or walk by yourself unless you were 'signed out' from the company's care (this also meant you couldn't use the paid for company accommodation whilst signed out). We had to write a blog every week, which only around 2 of which were actually published.
Communication with the company was shocking, they never replied to any emails or queries no matter how urgent etc. They also failed to take appropriate action when it came to one member's mental & physical health, which had consequences later on.. They also made not a single penny donation to the local school we taught at, which is disgusting considering how much we paid - and very awkward when the teacher told us this.
Overall on the whole trip I could not understand where any of this money had gone and was hugely disappointed. So much so that I actually came back early. We had one leader for around 13 people, which is not acceptable and too much responsibility for one person.
I would greatly advise you find a different company to travel with! I regret going with Frontier.
