A small grid, then the island
The capital is small enough to walk and small enough that a loud street is hard to escape if you are on it. Victoria Row in July is that street. A block away is a different night. Province House is your historical pin, not your front desk. If you need a car, you need it for the island, and you should ask where it will actually sit overnight. The centre is not built around large parking lots.
Read the island page before you assume Charlottetown is the whole trip. Cavendish and the north shore are summer context a drive away. Summerside is the other town. The Confederation Bridge is how many people arrive, at Borden-Carleton, not at the foot of Victoria Row. The airport is close, north of downtown. None of those facts makes this capital a beach hotel district. It is a walkable seat of government and history.
