Well, that depends. You can likely find cheaper prices to go to certain destinations, but not likely at the same level of quality.
Not only can you book the flight, the hotel, theme parks, and/or a cruise, but you can even book a car ride to get you wherever you need to be.
These days, travel insurance is a pretty smart add-on. However, you cannot buy a travel insurance policy through Costco’s Travel service.
With Costco Travel, you can set up payments, including recurring payments, once you’ve made your initial deposit, as long as the trip isn’t too soon after you reserve the trip.
