|Guatemala Immigration and Customs|
Their are two specific areas where this tidbit can be helpful:
1) Money exchangers > They can be found on both sides of a border so you have a lot of opportunities to exchange your old money for the new currency. Traditionally these exchangers should offer a rate better or equal to the bank. Check the exchange rate on-line prior to arrival as some will try and rip you off!
Here is how I handled the last shady exchanger. The current Guatemala rate was 1 USA dollar for 7.7 Q and when approached by an exchanger I asked right away "what is your best rate". He said 7Q for 1 U.S. and I said "sorry you lose and walked away" as he begged and upped his rate. I then proceeded to a group of exchangers and said "who wants my business and don't insult me with an offer of 7Q"! They flocked to me like seagulls on a dead fish and I got my rate of 7.7Q.
2) Entry/Exit fees > Know what the OFFICIAL fees are. Guatemala does not have an official entry fee, but I did hear that immigration will tell you there is a 20Q fee. And true to form I watched one tourist after another pay the 20Q fee while waiting in line. When it became my turn I handed my passport over to be stamped and then was asked for the 20Q. I responded in a very kind voice "sure but I will require an official receipt for that" and instantly my passport was stamped and she waved me aside for the next sucker.
