The Caribbean is a beautiful and diverse region with a wide range of vacation destinations, and the cost of your trip can vary significantly depending on factors such as the island you choose, the time of year you visit, and your travel preferences. That being said, some Caribbean destinations are generally considered more budget-friendly than others. Here are a few Caribbean destinations known for being relatively affordable:

Accommodations and food are generally less expensive than in many other Caribbean countries. However, it's important to research and plan ahead due to certain travel restrictions.
• Puerto Rico: As a U.S. territory, Puerto Rico can be a more budget-friendly option for U.S. travelers. There are various accommodation choices, from affordable guesthouses to larger hotels. Exploring San Juan's historic district and enjoying the local cuisine can be done on a budget.
