According to "Ask Sebby" ,the chase double dip doesn't work anymore.... Here's a link to the video explaining it <Mod note: Sorry, that link isn't allowed here. --UB>
TLDR: You will get hit with 2 inquires if you apply for 2 chase cards the same day....
SPG will also be a hard pull unless your already a AMEX member and being a AMEX member won't stop them from pulling your credit again for the Marriott.... That's two different issuers... Even if it's the same loyalty program....
Unless you already have a personal Amex card, a denial for an Amex should still result in a HP. Even then, YMMV. Even with your current stats, unless you've had a previous bad relationship with American Express, it doesn't seem like a denial would be likely.
If URs are what you want, I'd certainly agree that the CSR is a great match for your spending. Alternately, the Citi ThankYou Premier also fits quite well as travel is even more loosely defined and if you're spending that much on tolls (which is a LOT; that's like taking the Holland or Lincoln tunnel every single day from NJ!) I assume you have a lot of fuel spend, which is not a 3x category for CSR but is for TYP.
If you're looking to open several Chase accounts in a short period of time, I'd reconsider whether the SPG may be a better choice for you as Chase may not extend enough total credit lines to make 3 or more cards viable.
Also, I'm pretty sure I've recently seen DPs here on myFICO about double-dip apping on the same day with Chase without duplicate HPs. Many of us usually get two HPs for a single Chase app, but that should still prevent a person from receiving two HPs on each bureau pulled. As with anything in the credit world, YMMV. AskSebby has a very bad track record with giving incorrect information, particularly when it comes to Chase (examples: AUs are not eligible for bonuses when opening primary accounts, hotel cards not being eligible for PCs, etc.), so I would never suggest relying on information he has given.
