Where are you staying? One advantage or drawback of the DLE is the route. It stops first at the DLH, rarely but sometimes the GCH first, then at the DLH you may need a transfer.
The supershuttle often has mutliple stops too, but since it's smaller it can be nimble and quick at stops. But sometimes people are lucky and they are the first or only passengers.
If you choose either one they both have a coupon in the link below.
