As soon as it turns out that you will not be able to meet on time, let guides know that you will be late. You can find the guides' contact number in "My Trips" on your page. If you cannot connect to their phone, send a message to the guides and tell the guides when you will arrive at the meeting place.
If you cannot connect to the internet, please contact the guides as soon as you have internet access. Guides are waiting for you.
