Parking. There shall be, on site, one parking space per guest room, plus one space per employee, plus additional spaces as required by § 252-54 of this chapter for any accessory restaurant, conference, or meeting room, public assembly, retail or office uses, where said accessory uses are intended for nonstaying guests. Notwithstanding the above, where the hotel operates in a manner where at least 35% of its guests arrive and depart by mass or group transportation, the Village Board, in acting on the special permit, may reduce the entire parking requirement for the hotel to no less than 0.8 parking space per guest room.
