A Vanda inside the House? Advice Please?

[Triffid]

I have been thinking about getting a Vanda for some time. I have done enough research and know the basic requirements needed. Unfortunately Culture Sheets and the like do not always give you the full picture.

The main problem I have is that it would have to be kept indoors. No Greenhouse etc.
May I ask what Problems people have encountered when keeping Vanda's in this way and any advice people may have for me (and others for that matter)? The thing that is worrying me the most is the size issue. (If I do buy the one I want it will be the biggest orchid of the bunch thus far)

I understand that watering may be the main issue and the indoor set-up may have to be adjusted to suit (especially if mounted). Have thought about just keeping it in a vase, but would like to know of all potential options. Pros and Cons.

I have my heart set on this one
Vanda 'Lady Gray'

Any advice or experiences, Good and Bad, I would love to hear about.

Thank you in advance.
