Cattleya Walkeriana needs some TLC

[Optimist]

The stability issue is very importent. Pot clips, tie to wood inside the pot, zip tie to mesh etc. I have found that rootless orchids will survive if you water more consistently (they do not have roots and so cannot use the roots to create the food they need-- a lot of biochemical things happen in an orchid root). Placing the orchid in an area where it will not move, and where you cannot jostle it around is helpful to root re-establishment.
