TLE question

So I just PCSed and I just arrived to my next duty station, I haven’t signed in yet, however I got off post lodging at some hotel until Saturday. I was wondering if I made a mistake by not making a reservation through the IHG hotel? Will I still be able to claim TLE?

My last PCS I was reimbursed when I stayed off post. Also do I need to sign into the unit to start receiving TLE?
