Why does Parkes take Fiat

 Fiat currency will be accepted.
The decentralized PARKRES ledger will function solely with the native PARK token. Fiat is accepted only to provide an easier way for inexperienced users to directly purchase the digital token on the marketplace at the time of the park booking (instead of going through an exchange and buying Ethereum first). The decentralized backend/engine that handles the bookings, and all transactions between clients and hotels will operate solely in PARK.
