The Odakyu Romancecar is absolutely worth the small "Limited Express" surcharge for travelers heading from Tokyo (Shinjuku) to Hakone. For a relatively low additional fee (approximately ¥1,150 or $8 USD in 2026), you gain access to a direct, seat-reserved journey that takes about 75 to 90 minutes. This is significantly faster and more comfortable than the standard local trains, which require at least one transfer at Odawara and can be quite crowded. The primary "worth" comes from the experience itself: most Romancecar models feature massive, oversized panoramic windows, and the "GSE" (70000 series) model offers iconic "Observation Seats" at the very front or back of the train for a driver's-eye view of the scenic Japanese countryside. For those with a Hakone Free Pass, you only need to pay the limited express surcharge, making it a highly cost-effective way to add a touch of luxury and efficiency to your mountain getaway.
