If you have booked a holiday but want to do some planned activates when there, it is worth spending a bit of time researching what is available, close by, before you go. This will mean you do not waste time on holiday planning activities and can also save you money by allowing you to receive discounts on pre booked tickets or simply but giving you the time needed to shop around for the best deals.
If you want to go on a boat trip then you may be offered one through your tour guide. Many people turn these down knowing that they have seen the same trip cheaper being sold in the street. This is often the case, but you do need to weigh up the benefits of booking through your travel guide. If there is an issue and you cannot go, then your travel guide will often be able to move your trip to another day. If you have booked with a third party, the chances are they will not offer the same cover and therefore you will lose the amount you paid when you booked.
