I agree with the thrust of what you stated , My experience is the Credit Card Travel Insurance only cover the EU area? I paid a top fee to cover my many trip to Thailand . Just please check because trips really need to be covered by Travel insurance .
I used the Dental clinic at Mahidol University . I believe it is Teaching university . I had to wait to be clerked /ID done . I had Root canal work done . The treatment was excellent and not too costly .Needless to say I needed my knowledge to find /navigate this place . A good Taxi driver would know its location .
Look on Booking .Com while in the UK? You can find low budget hotels on the site .Also you can use the map to work out the proximity to rail/road /train links ?
I have been to the the Erawen falls , It was so good to cool off after the very hot day . The Commonwealth War graves was a very moving place to pay our respects .
I agree with what you said . As long as the person can read the signs /Reasonably mobile they will be ok . As somebody has said you can get assistance if you book a ride. I was a bit nervous at first time of visiting Suva , But I was being meet by an English mate & Wife . We usually just meet our Family by the Airport police office . Good luck .
