Conservative weather calls
Premium operators justify the fare with better hulls, enforced capacity limits and more conservative weather calls. That last one is the feature you are actually paying for.

Transfers
Twenty minutes of boarding chaos, a morning crossing with Agung behind and Rinjani ahead, and no vehicles on the other side.
Most boats call at Gili Trawangan first. If Gili Air is your base, confirm it is a named stop.
Padangbai, east Bali
Serangan, south Bali
The standard rhythm: hotel pickup between six and eight, twenty minutes of boarding, a morning crossing, and the Gili Trawangan beach jetty before or around midday.

Morning boats beat afternoon boats on comfort nearly every day of the year. The strait builds wind-chop after noon.
Boat plus hotel transfer both ends is usually worth it. There are no vehicles on the Gilis, and porters and cidomo carts meet the jetty.
That is roughly where a private hull stops costing more than three sets of tickets. Send the numbers and the desk will do the maths honestly.
