On our regular visits we take pesos, for tipping and buying souvenirs. But I know many people do take $1 bills for tipping.
We take sterling cash and keep it in the safe because if you take traveller cheques you dont get such a good exchange rate as cash.Then change as needed.
Only take $$$ for tourist card on entry or enough for departure tax if this not included in your holiday price.
