We added ALL of the lighting options. Wavered back and forth on them ourselves for the same reasons. Kids and teens LOVE them. They get some cool uhhhs and ahhhs from guests new to our boat. Heck, I even must admit to finding them pretty dang awesome in the evening and at night.
However, we really don’t go out too much at night. They really don’t get enough use by us to justify their costs.
IF you CANNOT get BOTH the lights, and more practical options, go practical. Not having practical options is the type of thing that will stick in your side when you want/need them. Not having lighting wont.
IF you can figure a way to spring for BOTH the lighting and other practical necessities, family and friends will likely get a thrill out of them. They certainly add an ambiance to the experience when boating towards the end of the evening into nightfall.
