It is most unfortunate that I am on holiday now in Thailand and my iPhone5 just would not switch on. I am desperate to know how I can get it done as information on subsequent travel are in the iPhone. Please help!

It is most unfortunate that I am on holiday now in Thailand, and just found that my Iphone5 does not switch on. I used it just a few hours ago and took some snap shots of the area. I did notice though that it seemed quite hot in my pocket hours earlier. I tried holding it on for a while on the switch on button but nothing happened. Tried re-inserting my sim card but nothing happened. I am desperate because I need to retrieve my travel information all contained in this dead iPhone. Please help. Thank you.
