We have a 26' and travel without a toad. We carry bikes, and don't hesitate to rent a car (Enterprise - they pick you up!), take the subway, or call a cab (Uber these days) on the rare occasions when we want a car. $ and hassle wise, we come out way ahead.
Most tourist areas have parking that will accommodate buses. We've found almost all of them are happy to accommodate our RV too. You won't be parking right in front of a big city attraction, but you can usually park within a few blocks. We can fit into a normal parking space _IF_ the back can hang over a grassy area. Occasionally we arrive early (an hour or so before the attraction open) to easily find a spot and then enjoy breakfast before the attraction opens.
90%+ of our travels are in places where parking isn't a big deal.
