Glad to see the chocolate and marshmallow conversation has stopped - I have a wedding dress to get into you know!
We went and looked round the reception place this weekend, and I marked out a place for my Grandma, a bit away from all the noise and hustle, there are some comfy chairs in the entrance room. They are also handily close to the toilets!
The reception is at a hotel, but in a function suite for weddings, if Grandma really wants to get away from it all she and my Grandad could go and sit in the lounge of the hotel and have a cup of tea, this would also involve a little walk outside, which she always seems to like.
I'll have the taxi numbers ready for when she's desperate to go home (one of my cousins, her granddaughter is an usher so I might ask her to be in charge of this).
All in all I'm feeling like things are bit more under control. I really hope she knows what is going on and enjoys herself a little bit.
Thanks for all your advice everyone, but if my dress splits at the seams I will blame you lot because of the chocolate talk!
