Labadee - can we walk the kids up to zip line but the adult not go?

Going to Labadee on Allure at the end of March for the first time. My kids - 16 and 13 - want to do the zip line, aqua park and coaster. My husband and I are not that interested in doing any of these. My question is, can one of us go with them to the start of the zip line and the other wait at the end? Same with Coaster? As far as the Aqua park, can we just stand on the dock or the beach and watch? Will they even let us book these excursions for the kids without an adult on the booking? Just trying to save some money and not have to pay for the adults but also don't want to leave my kids alone on a island in the Caribbean!

Thank you in advance!

For the coaster you can accompany them to the 'loading zone' and then wait for them to finish. It is roughly the same place.

For the Aqua Park you can watch them from the pier or the beach, although the beach is a further away and you might not be able to see them as easily.

For the zip line, they are loaded into a vehicle and driven up the mountain to where the zip line starts. Then all the people in the vehicle take the zip line down, so there is no way a non-paying person can do this. You can however, wait for them at the end of the zip line, back on the beach, when they are done - this is a good spot for some great pictures.

Adults are not required on the booking as long as the kids meet the minimum age and weight requirements. 13 and 16 year olds should have no problem with that.

Just my two cents: Labadee is an ideal stop for just hanging out at the beach - the water is perfect and warm. Nothing wrong with jam packing it full of activities, but that is a lot, and if you are trying to save some money, Labadee is one of the few stops where you can have a great day and literally not spend a dime. You may want to consider scaling the activities back to one (or zero) and enjoy the beach. There are a lot of free things to do there - volleyball, basketball, Bocce ball, Dragons Breath hike, hammocks, and, of course, the beach.

The "aqua park" is sort of a bust....and you can book that there...don't have to do it in advance. Wait and see if it's needed.
