Luke was never meant to enter. He was supposed to be the getaway pilot.

Lando, R2D2 and C3PO are supposed to break out Chewie, fetch Leia and Han, then all escape and get picked up by Luke.

Luke is just winging it after everybody missed the rendezvous, as Leia underestimated just how long Jabba and his entourage could wait silently behind a curtain.

The lightsaber was carried in by R2D2 as a backup weapon for Leia, who also came up with the plan.

[OrganicMSG]

She's got grenades and blasters down, so I suspect she could work out where the pointy end goes.

[saagarjha]

Well, those aren’t civilized weapons, are they?

[cgriswald]

Well, her civilization was wiped out a couple films prior...

[saagarjha]

Alderaan is a peaceful planet, so it’s not a great place to learn how to use weapons anyways…

It was a front for a terrorist organization, which is why the Empire freed every molecule of the planet with their liberation ray.
