The closest site to Quito to reliably see the Umbrellabird is Recinto 23 de Junio covered by Corey here and also written by me: here and here. Now the humble Ajila family has made a great effort and built a brand new small cabaña where you can stay the night before.
I stayed there with six other birders and it was very clean and comfortable. The food was also very good; I encourage anyone to visit this wonderful place and demand from you tour operator to see the Umbrellabird at 23 de Junio and
to stay with Luis Ajila.
I honestly believe that such effort has to be rewarded with your stay. Their rate is $40 per person and includes lodging, dinner and breakfast. Also includes a guide to see the Umbrellabird and a few other great birds that Luis will find you until noon.
This place is the grand prize for my conservation efforts to convince people like Luis Ajila that there is
a reason to conserve the forest and that a way of life can be achieved through sustainable eco-birding-tourism.
Here are a couple of shots of the place:
