I have a baby Tanglewood for camping trips; same size as a baby Taylor but cost less. It has great tone and playability. However, the body (being basically a normal shape but smaller) probably makes it less portable and more prone to damage when backpacking. (We camp by car so my main need was for something compact that does not take up too much space).

I do not especially like the tone of those slimline bodied travel guitars like the Martin and cheaper clones. I would be tempted to think about a baritone uke tuned DGBE personally, but I don't want to confuse matters further, when your enquiry is about travel guitars!
