We have been to Venice before (and love it!) and stayed in rented apartments in Dorsoduro. This time we will spend 2 nights in Venice post-cruise and would like suggestions for reasonably priced (eg. under $175/nt.) hotels that are walking distance from Piazzale Roma where we will catch the bus for the airport when we leave. Prefer a quiet location in Dorsoduro or Santa Croce and no bridges, or no more than 2, between the hotel and P. Roma as we will be walking with luggage.
