Does the Time Out Club have sessions for 4 year olds (the 'Crickets' section, I think) similar to the Bumblebees creche facility or is it just the activities listed on the website (eg. crafts, pirate and princess party etc)? If it is just these activities, do parents stay with the children? If there are 'ordinary' sessions is it possible to book them on the website? DS will be 4 when we go in June and I remember when he was younger we had to get this booked early as I know if fills up! Thanks
