Yes, suites are completely inside. I was at the very top row of the clubs, section 236- maybe I do have it backwards but swore it was opposote the rest of the stadium! Anyways, its a great but different experience up there. For me, with some disabilities, it was nice to be warm under the heat lamps and if it was really cold out go inside for a few, sit at the bar etc...
my advise- if you are planning on clubs next year get the top 3 or 4 rows as you are best protected/heated. Anyways enjoy the game today - ?
