Booked Sofitel Gatwick through lastminute.com (Secret Hotel), but when I arrived this evening informed they couldn't recognise my Platinum status for upgrade, lounge, late checkout etc.

According to the desk there was a memo of some description 3-4 days ago. Had no problem at the Sofitel Heathrow 2 weeks ago.

I don't have an issue with this, however it was a nice perk, it's just a bit of a shame. Anyone else found this?
