At my day job as a Product Development Administrator at a luxury tour operator, I'm constantly proofing passenger trip documents put together by in-house graphic designers.

I also noticed Starwood Hotels has a redesigned website with refreshed branding. Everything runs within a basic theme and layout, but each brand has their own quirks, if you will. For example, W Hotels are known for being trendy, stylish, vibrant, etc. and Sheraton would use words like warmth, hospitality, community... and their websites mirror their keywords quite well.
