A typical day for me it really depends on what type of tour you are doing. For example I could be doing bus tours which is bringing a group of people from A to B safely all while enjoying themselves. This would involve telling them about the area we are traveling through the history, folklore and key points targeting the points of interests all while making it light hearted. My goal really is to treat everyone like a friend not a history lesson they are the holidays and want to enjoy themselves and by the end I have a bus load of friends. I tell them good places to eat, answer any questions they have, make sure they know a return time to the bus and where to get it and everything in between.
Some days I could be doing food tours, describing the local cusine, other days I could be doing walking tours. Every tour you do , you have to take into consideration the type of group you have are they elderly , any mobility issues, are they students, is there first time in Ireland, where are they from, everything you can think off and all of this will allow for a more enjoyable day for everyone.
Pressures can present themselves in different ways. Time management definitely is one of the most important things for me you want them to have the best possible day and hit there itinerary with what they have planned to do. It's so important to stick to this or adjust it in ways that guests enjoy themselves and they are getting the full experience. Some things can go wrong that's out of your control, diversions on the road, bus break downs, guests falling etc Your dealing with the public anything can happen.
I find that you prepare yourself as best you can for all scenarios but most of all remain calm and collected the last thing you want is guests to feel stressed. So go with the flow things will happen but at the end of the day if everyone is happy and they enjoyed themselves that is the most important thing.
