I remember 2 check-ins at IC Davos where I got a pick from a bowl of rolled up prize tickets/vouchers. I kinda gently rolled my eyes expecting very little the first time around - and received a voucher for a bottle of wine from any bar/dining outlet. Which I was very pleased with, surprised to receive, and enjoyed tremendously. I don't recall exactly what I received the second time, something similar or free drinks etc, but I do remember looking forward to picking from the bowl that time.

I'd roll a dice for the chance of free car parking (just paid £24 last night at the IC o2) or pick a ticket for a bottle of wine etc all day long. But probably be less bothered and excited for the chance of 100 points or a kitkat upgrade.
