Although virtual reality technology is increasingly being used in tourism, its potential as a shopping tool and as an avenue for marketing and selling tourism products and services has not yet been examined. Likewise, very little is known about how exploring holiday packages through virtual reality affects behavioral intention to visit tourist destinations. This study aims to compare the visit intentions evoked and the process of booking holiday travel packages between an immersive virtual reality environment (displayed through Oculus head-mounted glasses) and a traditional web-based 2D platform. A causal model is proposed and tested for both designs. Using a between-subjects experimental design with a sample of 202 individuals, the experiences of two randomly selected groups were observed as they bought holiday tour packages to Rio de Janeiro, Brazil. The first group made a simulated purchase in an immersive virtual reality environment using a head-mounted device, and the second group made the purchase on a traditional e-commerce website. The findings revealed that the scores given to sense of presence, attitude change, and perceived ease of use were greater among those who made the purchase in the more immersive virtual reality environment. However, the relationships between the variables in the causal model were stronger for the classic website than for the virtual reality setting. Attitude change positively affected intention to visit a destination more in the virtual reality environment.
