Maybe somebody could help me decide on a big holiday destination? I have 3 weeks to a month, in late July/August. I have been looking at Costa Rica and Colombia and also Borneo and Cambodia but am open to other places too. We like to stay in small local hotels and tend to avoid the big chains, where possible. We like to travel by train but open to driving and short internal flights. We like nature, meeting local people, a bit of adventure and slow travel. Thanks in advance for your help and ideas.
