It is important to arrive about 10 minutes before the guruwalk’s start time. If you do not arrive on time, the guide has the right to give your reserved places to other travellers.
If you know in advance that you will not be able to arrive at the start time of the tour, I recommend that you contact your guru and let him/her know in good time. This way, he/she will be able to give you an alternative meeting point or send you his/her location so you can join.
