Is it worth it to fly to a cheaper beach destination?

Only if the flight cost is significantly lower. If you spend $400 more on a flight to save $200 on accommodation, you're losing money.

How do I find grocery stores in a tourist area?

Use Google Maps and search for 'supermarket' while zoomed out to include the town centers, not just the beach strip.

How to save money on a beach vacation

Save money on a beach vacation by booking lodging with a kitchen to avoid eating out, traveling in the shoulder season, and bringing your own beach gear. You can cut daily costs by 40% simply by avoiding beachfront restaurants and tourist-trap excursions.

Book a kitchen, not a hotel. Rent a vacation apartment or house with a kitchen. Breakfast and lunch at home save you roughly $40-$60 per day compared to beachside cafes.
Time your travel for the shoulder season. Visit destinations two weeks before or after the peak summer window. Accommodation rates often drop by 30-50% during these periods while the weather remains identical.
Pack your own beach kit. Rentals charge $20-$30 per day for umbrellas and chairs. Bring a lightweight, foldable umbrella and cheap microfiber towels to skip these daily fees entirely.
Use public access points. Avoid private beach clubs. Stick to public access areas where the sand is free and the crowds are often smaller.
Buy groceries inland. Never buy snacks or drinks at the beachfront convenience store. Drive 15 minutes inland to a standard supermarket to get prices 50% lower.
