Hey, totally get it, been there myself. First thing, talk to the hotel front desk. Sometimes they can extend your stay for a night or two at a discount or give you time to figure things out.
Next, call local churches, shelters, or 211. A lot of them have emergency hotel voucher programs for families just like yours. Let them know you’ve got kids and just need a couple nights. That usually gets you moved up the list fast.
You’re doing your best, hang in there. Help’s out there, even if it feels like it’s showing up on island time.
