Advice on going to a different group with no book!!

[Determined_one]

Hi all! I'm on holiday in Wales for the week and had intended on continuing going to a local group but just unpacked and realised I've left my book and membership card at home!!!

Does anyone know if I'll still be able to attend a local group without my book or card? Really don't want to have to miss a week if I can help it as I'm determined to stay on plan while I'm away!!
