As part of our trip to Italy this coming summer, our family of 4 will be driving from the Dolomites to Bologna in mid-July. Once we get to Bologna we're not 100% sure of our plans. We may stay for 3 days, or maybe 6 or 7. If we stay longer, we'll be doing trips to places like Parma, Ravenna, etc.
For much of our trip we are booking our rooms now. Generally speaking, what kind of options will we have in Bologna (or Parma, Ravenna, etc) if we show up and need to find a place to sleep that same day? Is this hard? For our trip to Italy we are generally booking rooms that cost $140 to $200 per night for the 4 of us. My guess is that it wouldn't be hard to find a place but we might have to spend a lot of money.
Secondly, does it make sense for us to keep our car rental in Bologna if we're traveling around the region? I don't mind trains and I've read here and elsewhere that for many people it is better to take trains. In terms of cost I think a car rental would be similar to the cost for train tickets for the four of us. Would keeping a car be a hassle with parking, route finding, traffic, etc? We do plan on eventually leaving the car in Bologna and taking the train to Rome and Naples (we fly out of Italy from Naples).
Thanks
