For calculating walking distances..... 20 blocks N/S = 1 mile.... ie: 42nd st. to 63rd = 1 mile. Crosstown blocks are longer going East West. Sat./Sunday is drivable no problem... forget about it on weekdays. Excellent bargain is 1/2 price "day of the show" ticket office in middle of Times Square - reconnoitre broadway musical matinee performances Wed and Sun for $20 each or less, and that aint bad.
