It turns out you can often get everything from GoPro camera rentals to curling irons sent straight to your room — free.

Phone chargers and adapters
If you forgot your phone charger or just don't have the proper adapter, check with the hotel's front desk; they will often lend out their extras.
Participating hotels include the Sheraton Puerto Rico, which just launched its Energizer Butler program that provides complimentary chargers for a variety of mobile devices. Ditto for Kimpton and Hyatt hotels.
Better pillows
Some hotels have been trying out pillow menus that allow guests to select their preferred pillows based on different levels of firmness, shapes, and suitability for sleeping habits.
Some help decrease snoring, while others were basically made for a lazy morning in bed. Conrad Hotels offer guests the option to select from their pillow menu or even pre-book their favorites though the mobile concierge app. Acqualina Resort & Spa also offers the service free.
Curling irons and straightening irons
For ladies who forgot to pack a straightening iron or curling iron, several hotels will have them on hand. Hyatt hotels,Kimpton hotels, and the W Paris-Opéra include these items in their list of complimentary amenities on request.
