On a budget, skip Go City Washington DC Pass — the spend outweighs the payoff.
~$80–200 depending on tier
A real ticketing product (Go City is the main DC pass operator), not an experience. It can save money only if you'll genuinely cram several paid attractions — the Spy Museum, a City Cruises trip, a hop-on bus, Madame Tussauds — into a day or two. The honest catch: DC's marquee museums and monuments are already free, so for most visitors the pass quietly loses money; it pays off only for a specific paid-attraction plan.
