過去研究利用不同研究方法找出在套裝旅遊中對消費者來說最為重視的項目行程，將這些重要因素加入套裝旅遊內以增加消費者的購買意願。但是，旅行社即便設計出一個最佳套裝旅遊亦未必能符合現今消費者需求的多樣化。本文將以三個實驗來驗證我們的假說。首先，相較於傳統的套裝旅遊，有彈性的套裝旅遊的確會促進人們的滿意度。接著我們會檢驗讓消費者執行兩種不同選擇任務的套裝旅遊時，其對最終保留行程項目數的差異。一種為允許旅客從完整型的套裝旅遊中刪去不喜歡的行程，另一種為消費者在擁有基本型套裝旅遊外，可從額外列的旅遊清單中選入喜歡的行程。研究結果顯示相較於基本型套裝旅遊，完整型套裝旅遊會讓旅客保留較多的行程項目數。最後就是區分出兩種知識程度的旅客面對兩種不同任務的彈性套裝旅遊時，對最終保留行程項目數的干擾效果。結果顯示知識低的旅客面對兩種任務的最終保留行程差異會大於知識高的旅客。
本研究發現的結果，拓展了以往對套裝旅遊的傳統設計方式的研究，並且提供一些後續研究的建議和管理上的意涵。

The previous studies used different ways to find out the most important trips item on which consumers would focus in the package tours, in order to enhance the consumers’ purchase intension. However, even though the travel agencies can design the best package tour, it still couldn’t meet the diversification of each consumer demand.
In this study, the hypothesis is confirmed by three experiments. First, the satisfaction is higher when tourists are presented to flexible package tours compared to the rigid package tours (experiment 1). Furthermore, the differences of item of selected trips are discussed, as the flexible package tours are classified into two option-framing (experiment 2). The option-framing is two-way method: leaving out the undesirable items from full package tours or leaving in desirable items from basic package tours. We find that consumers will have more trip items in their final selection under the former than the latter. And this effect is stronger for consumers with more tourism knowledge than those with less tourism knowledge (experiment 3).
The following research forms are provided through the results of this study, and some suggestions and the managerial implications are also offered for the future studies.
