Hello. We'll be visiting Vienna, Slovakia and Hungary and renting a car during our visit to Slovakia. Our visit to Hungary includes two full days in the Lillafüred area, where my wife has a family history, and then three full days in Budapest (also partial days for travel). Currently, our plan was to rent in Bratislava for our visit around Slovakia and return the car to Košice and take the train and buses to Lillafüred, where we're staying at the Hotel Palota. It looks like it's possible to take public transportation to the sites we're most interested in but at the sacrifice of time. Would anyone recommend keeping the rental and return it on arrival in Budapest instead? The price is almost double (so nearly 500 USD), which is not insignificant compared to our travel expenses. We're arriving in the Lillafüred on a Saturday, so the rental places in Miskolc are closed.
Thank you!
