Need a ride? Uber prices to surge during busiest hours of New Year's Eve

New Year's Eve: the day to overpay for everything from a that glass of flat Champagne to the impossibly-high heels you'll wear just once, to, once again, that ride home from Uber.

The ride-hailing app expects this New Year's Eve to be its busiest night ever. Due to high demand — and because it can — Uber is bringing back its surge pricing, a boon to its drivers but a bane to passengers. Fares can increase sevenfold or more during the busiest time of the night, which Uber says will be between 12:30 a.m. and 2:30 a.m.

To avoid spiking fares, Uber suggests booking a ride right after the ball drops at midnight, or wait until after 2:30. The app will notify users in advance if surge pricing is in effect, and full-price estimates are given before requesting a ride.

In addition to partying at home, taking public transportation or a cab, however, there are other options for revelers who, for whatever reason, think better of driving on New Year's Eve.

Riders who use rival Lyft will also see a version of Uber's price surge, called "Prime Time." The feature is turned on when ride requests "greatly outnumber available drivers." How much extra you'll pay, Lyft says, depends on demand. To check the rates, tap the Prime Time icon on the bottom right side of the app's home screen.

Flywheel, a much smaller competitor, is counting on sticker shock from surge pricing to win ever customers this year. From 8 p.m. on Wednesday until 3 a.m. on Thursday, the company is offering $10 rides in San Francisco, Seattle, Sacramento and San Diego, as long as the metered fare does not exceed $50. Rides that go over $50 will be charged the metered balance, the company says.

A service called BeMyDD (that's designated driver) lets you reserve a driver who will drive your car home for you in case you are intoxicated. Two drivers will pick you up, one to drive your car and the other to give your driver a ride once you have arrived home safely. Pricing can vary depending on your location. In Palo Alto, California, for example, it's $25 for a car pickup, plus $3.75 per mile.

Both Uber and Lyft are donating a portion of their New Year's hail to Mothers Against Drunk Driving. Uber will donate $1 from every ride when users enter the promotional code "MADDNYE" on booking a ride. Lyft will donate $1 for everyone who makes a "pledge" to get home safe by visiting Lyft.com/NYE.
