The Ultimate Business Bubble

Spent today working in Belgium and drove to Zaltbommel in the Netherlands in the evening to spend the next two days working there...pffff.

The hotel which I am staying at boasts the strange slogan "The Ultimate Business Bubble". Well, I can't make any sense of it...and the lady in pink invitingly opening her coat doesn't clarify things either, or am I missing something?

Any guidance from native speakers or other people with good control of the English language is welcome :)
