Here’s a crawl which would communicate some of this information:

The FIRST ORDER reigns.
Having destroyed the
peaceful Republic, Supreme
Leader Snoke now deploys
his merciless legions to seize
military control of the galaxy.

Taking command of the
last of the Republic fleet,
General Leia Organa flees
deep into uncharted space,
awaiting the return of
Jedi Master Luke Skywalker
to restore hope to the fight.

Fearing that they cannot evade
the First Order for long, Poe
Dameron has disobeyed orders
and sent two operatives to the
casino city of Canto Bight,
where a shrewd gambler may
hold the key to their escape…

Then have the Casino scenes up until they are jailed, then cut to Luke and Rey, then after some time has passed on the island cut to Leia traveling through hyperspace.

Interestingly, this makes TLJ much more of ESB in reverse, since the Resistance begins in deep space just as the Rebels ended in deep space.
