Just came back from there 3 weeks ago.  Outside, works great.  Inside - if you
are near the peremiter of the building on the ground floor, works good.  Deep
in the building like sitting at a table - forget it.  This was for everything
on the south side of the strip.  We never made it out to the other end.
Freemont street had pretty good coverage inside.

I never had a problem when I lived in Vegas but I didn't spend a lot of time
on the strip. Since Nextel has sponsored the new monorail project, going
'round the strip, I bet they've got it covered.
