如何预订旅游行程？

ToursOnTheWeb 不接受任何旅客或参与者的预订或付款。您可以便捷地在线搜索、比较和分享团体游、个人游和游轮行程。

行程详情页面会显示一个简单的按钮，点击即可直接跳转到运营商网站上的相应行程页面，您可以在那里咨询更多信息、查看当前空位或进行预订。与值得信赖的旅行社直接沟通，让您预订更安心。

重要提示：所有预订均受旅行社的条款和条件约束！

如何更改或取消预订？

Please contact the tour operator directly for your bookings, changes or cancellations. ONLY the Terms and Conditions of the tour operator apply to your booking - unlike bookings through traditional or online travel agents who may add a whole lot of additional terms and conditions of their own.

Your cancellation may be bound to fees, depending on the tour duration, when you cancel and how much you have paid. The tour operator will have incurred expenses that it may not be able to recover and now has to find someone else to travel in your place. Some operators allow you to re-schedule without a fine.

We always recommend obtaining a travel insurance that covers cancellations and medical expenses.

什么时候是旅行的最佳时间？

大多数人选择在旅游旺季出行，那时学校放假，气温也最高。对于带孩子去海滩度假的人来说，这或许是个不错的选择。但请记住，这些时期（欧洲和北美的七月和八月）也是旅游旺季，到处都会人山人海。

由于气候变化，近年来最热的季节变得更加炎热干燥，有时甚至会导致森林火灾和河流水位下降。游轮可能无法到达所有河段。有时气温甚至会高得令人难以忍受。

鉴于以上原因，我们强烈建议您在旅游淡季出行，也就是旺季前后。此时气温依然宜人，住宿价格更便宜，游客也更少，而且不会受到高温或干旱的影响。这才是最佳的旅行时机！
