包含多目的地和多目的游客对标准计数数据旅行成本模型得出的支付意愿估计值有明显影响，但差异在统计学上不显着。我们采用了Parsons和Wilson（1997）的更通用的旅行成本模型（TCM），该模型允许将多目的地游客纳入作为偶然需求，以便使用单一汇总公式来估计单目的地和多目的地观鲸付费意愿的公正衡量标准。标准TCM和简单广义TCM模型的主要目的旅行值相同，每人每天43美元，与区分联合旅行和偶然旅行的广义模型的50美元日值没有显著差异。一般模型避免低估了总的娱乐场所的好处，将导致省略多目的地游客的消费者剩余。
Inclusion of multi-destination and multi-purpose visitors has an appreciable influence on a standard count data travel cost model derived estimate of willingness to pay but the differences are not statistically significant. We adapt a more general travel cost model (TCM) of Parsons and Wilson (1997) that allows for inclusion of multi-destination visitors as incidental demand to allow estimation of an unbiased measure of single and multi-destination willingness to pay for whale viewing using a single pooled equation. The primary purpose trip values from the standard TCM and simple generalized TCM model are identical at $43 per person per day and neither are significantly different from the $50 day value from a generalized model that distinguishes between joint and incidental trips. The general models avoid underestimation of total recreation site benefits that would result from omitting the consumer surplus of multi-destination visitors.
