While making reservations for the hotels, I would read the information about taxes, which is also described in the LP Guidebook:
"Based on local tax laws, Peruvian citizens (and foreigners staying more than 59 days in Peru) must pay an additional fee of 18%. To be exempt from this 18% additional fee (IVA), a copy of the immigration card and passport must be presented.
Please note both documents are required for fee exemption. Guests who are not able to present both documents will be required to pay the fee."
So I guess, we just need to ask for this immigration card, which I suppose we will have to take anyway on the passport control upon entering the country. And show that with our passports. Somewhere they would ask for a copy of documents, now I don't know if they really require a copy or if they can make one on their own.
(I've also read in one or two articles on internet, that sometimes they want to give you visa, which you don't need if you are staying just for a short period, and that we should refuse that, since that visa prevents you to skip paying the tax.)
Does anybody have anything to add/confirm..?
