Layover with duty-free bags

I have never purchased anything duty-free before but I'm planning to before my flight to the US (where I'm a citizen).
However, I'm leaving the airport for a hotel. I don't normally check a bag. What can I expect with my duty-free alcohol purchase? Can I bring it back in the duty-free bag and keep it on my carry on for my second, domestic leg?
Or should I plan on checking a bag for the domestic leg with the alcohol?

Can you take duty free on a connecting flight?
You can take duty free liquids onboard your flight to the US. If you'll be transferring to an onward connection after landing in the States, you should pack your duty free liquids into your hold baggage at the transit point (take care not to exceed your baggage allowance in doing so, though).Do checked bags get transferred on layover?
Unless the connecting flight takes place in a country that requires all passengers to go through Immigration and Customs, checked baggage will automatically be transferred to the next flight.Do you have to collect your checked bags if you are connecting?
It depends on how your ticket was booked. If your flights were booked under one ticket, your bags will be checked through to your final destination. If your flights were booked under separate tickets, you will need to collect your bags and recheck them before your connecting flight.Do I have to pick up my bags on a connecting flight international?
If you're connecting in the U.S., they require everyone from international flights to re-check their baggage upon the first landing point.My HUGE mistake at JEWEL CHANGI | Exploring SINGAPORE'S CHANGI AIRPORT TERMINALS 2019
