I think staying on North Uist would be better, you're close to the RSPB reserve.
Are you camping? You can pitch your tents in certain places on the reserve, check with the warden, he is very helpful. It was too windy when we were there, and the tents were suffering, so after one night we decamped to a wonderful hostel on Berneray: http://www.gatliff.org.uk/?page_id=9
I didn't want to leave there! You can't book in advance, so get there early and put something on a bed! Alternatively you can pitch a tent there.
