It certainly looks like an Vandaceous orchid, but I don't think you can be 100% sure it's even any kind of orchid without seeing a flower (or DNA test).
Orchids are defined by having a fused column instead of pistils and stamen.
Agreed, Vanda alliance, Aeridinae, eventually close to Luisia. There will be more plants, if you take a second look, and possibly you'll find flowers at one time of the year.
