I also grow some orchids and succulents. I don't grow them together in one pot, they have their own individual containers. Or I group some succulents together, provided they have similar growing attributes.
Some succulents are summer dormant, and orchids are happy during warmer conditions provided they get their watering and lighting needs, so you have to consider that when you group your plants.
I have to consider their watering and air ventilation needs. During summer I have the orchids outdoors in my growcamp where air circulates well and I can freely water the plants. When seasons go colder then I move the orchids indoors, except for cymbidiums, they can handle our mild winter here.
Because our area is extremely dry and no summer rains here at all, our full sun is scorching in summer, I have to position some succulents in shadier areas. The canopy of city trees further protects them from the heat of the sun.
There's a wide range of orchids to grow, I fail miserably on some types, but so far Oncidiums tolerates my conditions here very well. I have learned to expect too that when our long, dry conditons are here and temps soar consistently from 90F and higher everyday, no blooming expected here. The plants will wait it out till the more tolerable 70F to 85F returns.
So consider very well your growing area, it maybe tempting to put them in one container, but the reality is the plants have varying growing needs.
Speaking of Schlumbergeras, I only keep them indoors here too by our west facing window, they will get fried here by our full sun and very dry conditions. They seem to like the area where I grow my Phalaenopsis orchids, so they are in that spot in my house, in their individual containers.
