It’s wonderful you want to support a fellow DISer. However, We try to keep talk of using or soliciting specific person’s referrals off the DIS per this board’s rules.
I don’t think
@palhockeymomof2 mentioned this in her recommendation, but I must caution you that if don’t already have a relationship with Amex (the longer, probably better), be prepared to commit yourself to keep spending on your Hilton Biz long after you’ve met the MSR on that card or risk being labeled a “gamer” who is only opening cards with Amex for their bonuses, and ceases (or significantly reduces) spending on the cards after you’ve met the MSR to earn the bonus. In the past half year, Amex has really stepped up their efforts against churning — some would say overzealously so. If your history of opening and closing cards, or spending pattern lands you on this naughty list, Amex will start displaying a pop up warning that you are not eligible for a bonus the next time you try to apply for a new card with them, or worse yet you may not even get the pop up warning and find that your bonus never posts despite meeting MSR, and when you inquire Amex will tell you it’s denied because of rewards abuse.
The Hilton Biz is a good card. Most importantly for you right now, it won’t add to your 0/24 count and you can save those slots for Chase. It earns 12x Hilton points when used to pay for Hilton stays, and gives you complimentary Gold status that will give you another 18x Hilton points for hotel stays. Gold status gets you upgrades and breakfast too. Since you have an eBay business, the Hilton Biz earns 6x Hilton points on shipping. When you spend $15k on the Hilton Biz in a calendar year, you earn a free weekend certificate, so that provides some incentive to keep spending on the card. The Hilton Biz comes with 10 Priority Passes that’s nice if you don’t have another card that gives you a membership. But the Hilton Biz does carry a $95 annual fee that’s not waived.
Hope this helps. Good luck!
