I have just registered on quidco.com and found Marriott is offering 4% cashback when booked via the site.

When I click it takes me straight through to the Marriott site - without the whizzy new graphics (hurrah) and I can see my MR number automatically filled in.

Like everyone here, I'm a pointsfreak but the opportunity to save an extra 4% on all my bookings (especially as its cashback so in effect I get 4% on my business expenses credited to me personally) seems real fab, if, but only if, my MR points and elite nights are unaffected, otherwise the points represent better value.

So, here's the question, if I book via Quidco, will I get MR points, PLT benefits and elite night credit for the stays, or just the 4% cashback?
