Having just received a SIXT Platinum (comped from HHonors Diamond), I've booked a holiday car at SIXT PMI (Mallorca, Spain) for 11 days in July at a fair price. All my professional car rental has been in the US, so I have no SIXT experience up to this point.

I'd like to make sure I "Double Dip" and receive both HHonors points (hopefully 5000 for first Platinum rental) and SAS Eurobonus points (1500 special offer until end of july).

I booked a Internet rate, and put my Platinum number in the comments field as suggested in this forum. As FF program I put in SAS.

Do I need to do anything before pick-up to ensure I get both Hilton and SAS points ? Or can I just have them PMI station enter the Hilton and SAS details at pick-up ?

Apart from the points, of course I hope for a upgrade (booked EDMR, e.g. VW Polo). Any experience with PMI treatment of Platinums ?
