How much in pesos should I bring to Mexico City for a week-long escapade? With a plethora of captivating experiences awaiting in this vibrant metropolis, it raises numerous considerations. Is it prudent to bring a substantial amount for spontaneous adventures, or should one lean towards a more conservative figure, reserving funds for unexpected expenditures? What about the different costs associated with dining, public transport, and admission to iconic landmarks? Would it be wise to rely solely on cash, or should I supplement my pesos with a credit card for added security and convenience? As I prepare for this enriching journey, how do exchange rates play into the equation? Are there hidden fees that may lurk around the corner when converting currency? Furthermore, should I anticipate attending local markets, where bargaining is the norm—will I need extra pesos for that exhilarating experience? Such inquiries swirl in my mind as I plan this adventure.
