Payment OPSEC, A question

I've been in this world for a while and using dayuse hotel services with hotels who accept cash has always been my preferred method.

My wife and I share access to all of our financial accounts, even though I handle all the finances and she barely ever looks at stuff, I work hard to keep all transactions out. (Cash is not an issue). Dayuse let me do a reservation with a different email and then pay cash at the hotel.

Lately, Dayuse (the best booking platform, IMO) has started charging $5 for an online booking fee for a cash payment hotel. I can guess that other services (like hotelsbyday are not far behind).

Having one of these in my credit card payment history is not an option.

I had an old greendot debit card but those require ID verification to reload. I'm not sure I want mail from greendot coming to my house. I don't want to go have to buy a new debit card at a convenience store every time I need to make a payment.

So, my idea and question is this:

I have a couple bank accounts at a bank that we barely use (emergency stuff). Getting mail from that bank is normal. I'm considering opening an entirely different debit account there until a totally different login. Since receiving mail at home from this bank is normal (as is having a card from them in my desk), I figure the risk is very low if I just keep a low balance there and keep it at a separate online login.

Is there anything else I'm not thinking of from an OPSEC perspective? Or any other ideas?
