Swings sure are fun! But better then just regular swings are the ones made for couples where two can fit on it! Well, granted, two adults, so with cubs maybe even a third would fit...
You usually can't swing as high with those - at least you shouldn't - but they can make it work anyhow. Plus the fact they're playing together does make it a lot more fun.
Plus, who says it's only for couples? It fits a couple of cute twins on it just as well and they're even cuter!
