Planning a big trip which will involve Hong Kong, Burma, Bangkok and a lot of travel (all sorts of modes) through South America - which is best to take. Rucksack or wheeley suitcase??
I'd recommend a rucksack as the pavement will be rough at times (possibly non-existent) and it's not uncommon to see people struggling through some of the transport hubs and train stations with wheeley suitcases. Also, it's always nice to have two hands free and the bag attached to your body during ticket checks, immigration, and negotiation with taxis/tuc tucs/drivers.
