Dear Jongyun Choi, The difference between the two tour codes you have provided is that tour 2-115 has the Los Angeles Hotel upgrade option in the booking section, at an additional cost. If you do not wish to have the upgrade, you can keep the standard 3 star hotel quality for the regular price. Tour code # 2-115 already has the Los Angeles Hotel upgrade in the tour price, you are not given the option to select it. The difference between the tours are oftentimes found in their start cities, tour durations, the highlight locations covered, and the quality of hotels booked as part of the package. The itinerary of the cities for each tour is listed on the tour page, however please note that order of day-to-day itinerary is adjustable depending on tour start day. You may find similar tours on our website in the scenario that if one tour is sold out for your dates, you can have another option to choose. Best Regards, Tim Customer Service Rep
