On Board tours are different. They’re shuttle size buses, not big double-deckers.  You’ll make several stops along the way on your tour and your tour guide will get out with you and provide a guided walking tour.  The tours are limited to 35 people or less. And they even provide free bottled water.

Currently, they’re advertising a 15% discount on their “NY See the Best Tour” with promo code SALENOW2

On Board Tours gets very good reviews at TripAdvisor.
