Birthday Party testimonial, September 2025

“This was an unusual party as it was for a sixty year old. Living up North, with children and grandchildren all over the country, it was about finding the correct venue for an event, which would allow the children to have fun and the adults to have time for talking and catching up… It has made some lovely memories for my husband, and hopefully something the children will remember for many years to come.”

Birthday Party testimonial, December 2025

“My son had a wonderful 5th party at The Postal Museum. Him and his friends had the best time and will be one that we remember for years. We loved how the Sorted! space was exclusively for us.”

Birthday Party testimonial, April 2026

“We had such a wonderful experience celebrating our son’s birthday at the Postal Museum. Everything was very well organised, and the team was incredibly helpful, friendly, and attentive throughout the entire event.

The children absolutely loved the SORTED! indoor soft play. The space was great for hosting the group, and everything ran smoothly from start to finish, which made the day very easy and enjoyable for us as parents.

Thank you so much for helping create such a special and memorable celebration, our son had the best time, and so did all of our guests.”
