What people love about 3-week UK and Great Britain tours
- Britain and Ireland Panorama (19 Days)
Itinerary was strenuous - sometimes we didn't get to hotel until 10:00. Also not enough time at most stops
- Grand Tour of Britain & Ireland
I wanted to see as much of UK as I could .. and that us accomplished
- Great Britain and Ireland (Age 27-35)
The trip crams all the best sights and scenes of Great Britain and Ireland into 18 days with highlights being exploring the streets of Edinburgh and partying the night away in Dublin and Belfast. Jacob gave the trip a special flair with his witty humour, comprehensive knowledge of the history of the areas we travelled to as well as his overall enthusiasm for travel. He made a special effort to connect with each of the travellers individually to ensure their experience was positive. Having an enthusiastic, smiling ball of energy at the front of the coach each morning made the experience that much more enjoyable.
