While a pricey European getaway sounds dreamy, there are tons of more economical summer hotspots in the US that we would gladly use our vacation time to visit. But whether your travel plans involve trekking through one of the gorgeous National Parks or hitting up the country鈥檚 best art galleries, there鈥檚 one travel necessity that always confuses the heck out of us: tipping. So, in an effort to better understand the tricky etiquette of tipping when you travel, we鈥檝e enlisted the help of Sharon Emerson, rock-star travel agent and owner of Cruise & Tour Planners, to create a definitive list of places you should tip on your stateside vacation 鈥 plus the exact amount that鈥檚 considered polite for good service.

1. Housekeeping: Whether you鈥檙e a messy Mary or a tidy Tammy, it鈥檚 always polite to leave a little extra moola for the folks who clean up your hotel room. Emerson advises leaving $1-$2 per night on the bed. Just make sure to leave a note saying it鈥檚 for housekeeping so they know you didn鈥檛 just leave your spare change behind by accident.

2. Room Service: Even though you鈥檙e probably itching to dig into your gourmet grub, don鈥檛 forget to tip the hotel staff member who brings up your dinner. Emerson suggests $5 per delivery to make things easy.

3. Bell Service: If you鈥檙e going to enlist a staff member鈥檚 help to transport your luggage from the car to your hotel room, it鈥檚 definitely considered a faux pas if you don鈥檛 tip. Although some people claim $1 per bag is plenty, Emerson notes that $5 per delivery will more than cover it. Plus, it means you鈥檙e not frantically counting bags to make sure you鈥檝e tipped the right amount.

4. Luggage Storage: Arriving before your check-in time? Don鈥檛 worry, most hotels will store your bags free of charge. Just make sure to tip them $1 per bag when you pick them up.

5. Car Parking Valet: Whether you鈥檝e rented a car for your vacation or are driving your own vehicle, the standard amount to tip a car parking valet is $5, according to Emerson.

6. Hotel Restaurants and Bars: If you鈥檝e decided to eat in your hotel鈥檚 restaurant and bar instead of venturing outside, be aware that you won鈥檛 get a discount on tipping. Emerson advises using a standard 20 percent tip for adequate service.

7. Concierge Service: While there鈥檚 no obligation to tip a concierge for simply answering your questions, you should definitely give them a gratuity if they book you hard-to-get tickets or reservations. Emerson suggests $10-$15 depending on how many people they serve and what level of help they provide.

8. Group Tours: Art museums, historical landmarks, thrilling theme parks鈥 there are tons of places that offer super informative group tours for a fee. But even though you may think that the pricey tour price covers your tour guide鈥檚 salary, it鈥檚 still polite to tip your guides $5 per person for a half day or $10 per person for a full day, Emerson suggests. Plus, if your tour involves a driver, tip them $2 per person for a half day or $5 per person for a full day.

9. Private Tours: If you鈥檙e going to splurge on a private tour, be aware that you鈥檙e probably going to have to tip them a little more than a public group tour. Emerson suggests upping the gratuity to $10 per person for a half day or $20 per person for a full day; for tour drivers, $5 per person per half day or $10 per person for a full day.

10. Ski and Snowboard Instructor: If you invest in ski or snowboarding lessons in the winter, you should definitely consider tipping your instructor. 鈥淎lthough ski lessons are expensive to the customer, chances are the instructor themselves are only making $10-$15 per hour. If you think of an instructor that has 10 kids in a group all day, they may make as little as $60 for playing instructor, parent, and chef,鈥 says Mike Ma, chief product officer at Snowvation. He suggests 20 percent is a good rule of thumb to spend. 鈥淭hat said, instructors know skiing and snowboarding is expensive, and most instructors are appreciative of anything you give since many skip the tip entirely.鈥

11. Wine Tasting: Planning on touring a winery during your summer vacay? 鈥淚f visiting a winery for tastings, it is appropriate to tip the server $5 or $10 unless you purchase wine,鈥 say Pam and Larry Willis of The Gables Wine Country Inn.

12. Take-out: While sitting down at a restaurant will run you at least an extra 20 percent tip, Emily Post鈥檚 famous General Tipping Guide advises that there鈥檚 no obligation to tip for take-out. Just be aware that you *can* tip an extra 10 percent for curb delivery or for a large, complicated order.

13. Home or Hotel Food Delivery: If you鈥檙e planning on getting food delivered straight to your door, it鈥檚 a good idea to keep some extra pocket change to tip your delivery driver. Emily Post suggests 10-15 percent of the bill or $2-$5 for pizza delivery, depending on the size of the order and difficulty of delivery.

14. Bartender: The days of stressing about how much to tip your bartender are over, ladies. Emily Post gives it to us straight: $1-$2 per drink or 15-20 percent of the entire tab. Easy!

15. Hair Appointments, Manicures, or Massages: Now that you鈥檝e decided to treat yourself to a special spa day on your US staycation, you鈥檒l probably need to know how much to tip your awesome manicurists and salon staff. Emily Post suggests tipping 15-20 percent of your total bill 鈥 and if multiple people serve you, make sure you specifically ask for your tip to be split among everyone who helped you get glam.
