“We truly had a tailor-made outing. Great communication with Tim – he was always available and very flexible in the planning.” A fantastic team outing for 80 people, organised by Uitjesbazen. We played the Wie is de Rat game, and it exceeded all our expectations! Before the event, I had excellent contact with Tim – he was always reachable and very flexible throughout the planning process. We truly had a tailor-made outing. The team members who hosted the game during the day were also very enthusiastic, and the prize ceremony was a real highlight. I would definitely recommend this to others. Tara Boute Amsterdam – 80 participants Who is the Rat
“And the team received all kinds of fun challenges. Sometimes it led to truly hilarious moments.” What a fantastic evening we had with our pop choir! We were with 30 members, split into groups of six. Using an app you had to download, a Rat was randomly assigned within each team. And then the team received all kinds of fun challenges. Sometimes it led to truly hilarious moments. It was set up very professionally. The organisation even arranged a prize for the best team – and for the best Rat. All in all, it was a hugely successful friends’ outing! I’ll definitely be trying out more activities in the future! Astrid Matthijsse Helmond – 31 participants Who is the Rat
“It was a great success – we had such a fun afternoon!” Highly recommended! Communication in the run-up to the event was smooth and quick. Tim from Uitjesbazen really helped us think through the options for the location and drinks. On-site, we were guided with great care and enthusiasm. It was a great success – we had such a fun afternoon playing the Who is the Rat game! Leonie Klinkenberg Amsterdam – 50 participants Who is the Rat
