When not surging, the Uber/Lyft rates from the airport are comparable to the taxi flat rate ($36). But that taxi rate is only for 1 or 2 people. More than that, the fare is $15/person, so with a party of 4, it'll be $60. Keep in mind as you compare rates.
In general, I expect ride share rates will be pretty high on parade days. Tonight, plus next Mon/Tue, things should be more reasonable.
