Uber for 2 is a great thing. When it's 8, it becomes much more complicated (and costly). That's where DME was great for our party. Simple to plan and just roll with the start to the trip.
Ubers also don't fit a standard family of 4 with young kids and luggage/stroller. Even an Uber XL doesn't.
Yes, that's why my post emphasized that it works for us because there is just two of us and that I understand it wouldn't work for families, etc. as well as ME did.
