What hidden costs should I check with boutique hotels and adults-only stays?

Boutique and adults-only properties can provide quieter design-led stays, but “adults only” does not necessarily mean romantic, private or nightlife-oriented. Ask about deposits, taxes, service charges, utilities, cleaning, electricity, internet, parking, guest fees and early termination. For property, include transfer fees, common-area fees, maintenance and legal due diligence. Booking note: Confirm the exact location, room type, noise exposure, cancellation terms, deposits and guest policy directly. “Central”, “beachfront” and “sea view” can describe very different layouts.
