Generally, you do not need to bring your own beach towels to an all-inclusive resort. Most mid-to-high-end resorts in popular destinations like Mexico, the Dominican Republic, and the Caribbean provide complimentary beach and pool towel services as part of the "all-inclusive" package. Upon arrival, you are often given a "towel card" that you can exchange at a dedicated poolside hut for a fresh, dry towel. You can typically swap these throughout the day as they get wet or sandy. However, there are a few caveats to consider: some budget-friendly resorts or boutique hotels may require a small refundable deposit for towels to prevent theft, and others might have a limit on how many you can take at once. While it saves significant luggage space to leave yours at home, some travelers still prefer to bring a thin, quick-dry microfiber towel for off-site excursions to public beaches or cenotes where resort towels are not allowed to be taken. If you are staying at a major brand like Sandals, Iberostar, or RIU in 2026, you can safely assume that high-quality towels will be waiting for you by the water.
