i too am an acoustic guitar nut and although settled now in last 5 years i was travelling my whole life and have in depth investigated travel options........however the forecast is bad.....as any small acoustic travel guitar is mostly horrid .......... tonally they suck even the expensive ones.they just too small to have a good sound.......
HOWEVER i have recently discovered the vox mini3 batterry amp..........
they cheap about R1500 retail and about R1100 0r cheaper after the store gives discount ......... so very inexpensive but very nice.....
only 3W but pretty damn loud...and it has modelling and fx on it and 2x channels plus an aux input for ipod so it can take 2 instruments or a guitar and mic...........
i own 2 of them .......since i came to the realisation that they louder by far than any acoustic and are battery powered by 6x penlights (which means they can work anywhere in world with an easily available battery ) they also have a power supply but battery life is an incredible 27 hours ...... or longer ........ and can work on rechargeables too.........
the amp looks cool and i have 2 in white tolex .......
so now when you travel .......you can take an electric guitar which is built much more solidly to survive travelling and just pop this little amp into your suitcase ............
it;s pretty small and has great sound (truly one of the better small battery amps around ...the only other contender is the roland mobile cube but i prefer the features on vox for my needs ) .....and tough enough to take any knocks but small and light enough to take a small corner of your suitcase .. and battery power with a AA size battery's which are available anywhere (and battery life is real long ) all for about 1K ........
and a bonus is if you put an ipod thru it you have music where ever you are too.......... so not just for your guitar
if you don't believe my take on this ask icecream man (on forum) .....he showed his one to me and i was blown away and ordered mine the very next morning ........ it really sounds awesome and fully featured for the price ............
so i would take my mini 3 and an thinline acoustic like the yamaha silent guitar or even an electric guitar and be having great sound wherever i went ........
check out the amp on the vox site

i even have an idea to build this little amp into a guitar case ..so have mobile sound in one case .as airlines as long as you tell em in advance often allow one guitar case as "free " extra baggage ........ so an amp and guitar in one case is a great solution
so this amp has changed the way i see travelling with a guitar and means less stress about damaging that lovely acoustic and NOT having to try and put up with a thin twangy sounding travel acoustic, if you not heard a travel guitar just listen to a martin backpacker (marshall music woodmead has one ) ... or a washburn rover... or even the more expensive ones like baby taylor ..in fact any acoustic made with smaller bodies and you know it's a thin sound that has little volume and sounds more like a large ukelele than a full size guitar ......
and another concern is many of the travel guitars feature shorter scale length so unless you have tiny hands you will find it small to play on..
of course the other option is just buy a guitar when you arrive............. a full size acoustic ..... i've travelled thru much of the world and never yet NOT found a guitar store somewhere even in small places like bahrain ....then just buy a descent enough acoustic to satisfy your taste and donate it to someone when you leave ....... sometimes thats the cheaper option than dragging stuff around /risking damage and theft and taking up your weight allowance for flights
btw i have no affiliation with vox............ BUT i think this battery amp is a winner
