On a budget, skip Odaiba — the spend outweighs the payoff.
Free to wander
A breezy, family-friendly waterfront with a life-size moving Gundam, big malls, a small replica Statue of Liberty and skyline-and-Rainbow-Bridge views — easy and fun with kids. The honest read: it's a modern shopping-and-entertainment zone, a bit dated and soulless to some, and a hike from central Tokyo for what it is.
