Well then, if you can have phone contact with your Lama or an experienced practitioner during the retrat "just in case", then there is no reason for you to not do it at home. The only thing you may need to do is see a Lama at the end of the ten days to check for signs of sucessful completion.
"When one is not in accord with the true view
Meditation and conduct become delusion,
One will not attain the real result
One will be like a blind man who has no eyes."
