Bon Voyage comes with new matching furniture, which you'll see in various accommodations in all three destinations. Also, the Comfort category comes with two new objects: the tent and hammock.
This is the new tent object. With this, your Sims can go camping, and you can create campground community lots for your custom-made vacation destinations. The tent can also be placed on your Sims' home lot.
Up to two Sims can get into a tent at any one time, and child Sims and older can use them. A Sim that is already inside the tent can invite another Sim to join them. Sims can sleep in tents, but they aren't very comfortable, nor do they completely satisfy your Sims' Energy need. When two Sims are inside the tent, they can talk to each other.
The tent is a new place for your Sims to WooHoo/Try for a Baby. It counts as a public WooHoo.
Sleeping in a tent also earns your Sim a Vacation Memento.
The hammock is another new object in Bon Voyage. Child and older Sims can use it, and it has a number of interactions. Sims can relax in the hammock, which satisfies Comfort. If a Sim's Body skill is low, there's a chance that they'll fall out. Sims can also play on the hammock, fulfilling Fun as well as Comfort. Whilst relaxing in the hammock, Sims can daydream, satisfying Fun and Social as well as Comfort, and they can also read a book, satisfying Fun and Comfort. If a stereo or TV is nearby and your Sim is in the hammock, they can watch the TV/listen to music.
Sims can also WooHoo/Try for Baby in the hammock. The interaction becomes available when one of the two Sims in a high-enough relationship are in the hammock. Either Sim can initiate the action.
