HUH? There shouldn't be any difference between Caribbean and other places regarding whether companion tickets are eligible to use RUCs/GUCs or not.
Caribbean versus other destinations affects whether RUCs can be used for upgrades. If you can use a RUC to upgrade yourself on the flight, you can also use a second RUC to upgrade ONE companion on the same PNR, assuming that upgrade space is available.
