As a plain ol’ Spire I’ve never yet received free lounge access at any IC I’ve stayed at but in my travels around the U.K. Crowne Plazas I’ve found lounge access has no real consistent rule. My experiences so far this year are:
1. Given to Spires as a matter of course: Birmingham
2. Given to Spires as a welcome amenity option: Liverpool Airport & Solihull
3. Given to Spires only as a room upgrade to club level room: Nottingham
4. No free access to club lounge: Stratford-Upon-Avon
