I currently have the "old" $49 card, which gives me a 10% rebate on points nights. I'm also an Ambassador member, which gives me an additional 10% rebate on points nights.
Can I get the new card and stack the 4th night free plus the 10% + 10% = 20% rebate on points spent, while also buying said points at a discount as a new cardholder?
Unfortunately I've already maxed out point purchases for this year under the 100% buy points bonus last month.
