It's great how you are planning so well for your little bun
If you do get a chance to go for some hay from a farm take a single quilt cover to collect the bale in as it really cuts down the mess. You can get a cheap one from wilkinsons for around £5.
Toys for buns are a good idea as it keeps them stimulated. Do you have a garden centre close enough to travel to? Even if you just go occasionally you can pick up bunny things there. Wilkinsons also have some things for buns such as willow balls to play with.
