To answer your question, the taxis regularly take people over to Trellis. It is a stop and it is on their rate card. They probably will bundle your guests with a few others.

There is usually one or two of the places open there in Trellis. At the very least grab a cold one from the market and have it outside if the bar is closed.

You mention luggage and perhaps you are not comfortable picking up with guests, coolers and bags. Those charter dinghies get pretty small. If you do go that route, make two trips and be very aware of where the coral heads lay. One easy way through is just to follow the moored and anchored boats.
Have fun.
