If you did want to enter some rabbits, you will have to pay a late fee as the entry date has probably passed (the show is tomorrow). Depending on the show, the fee could be about 50 cents more than the regular fee. The show I am attending next weekend is $3.50 for the regular fee and $4 if you enter late. You will need to arrive early, usually an hour before judging to sign in and pay the fee. If you do bring some, limit yourself to 1 or 2 so you can get them to the judging table and not be too stressed trying to figure it all out. You will need to bring them in carriers with food and water as well as your grooming items and any other stuff you may need for them.
If you aren't going to enter rabbits, don't bring them. They will probably be stressed by going to the show and it is not a good idea to bring them if you aren't going to show or do something with them (breed or sell).
Since it is your first show, it might be better to just go without the rabbits and see how it is all run. Find someone you can talk too about showing and even offer to help if needed. Hang around the judging table for a few classes to see what goes on there, if you have a specific breed you want to see make a point of being there for that breeds judging. There can be other stuff going on like raffles, pet classes and auctions that you can check out and even participate in.
Plan to be there for a while, so bring food and water and even a chair. If you bring rabbits then you can have a place to set up, but without rabbits you just have to find a place where you can sit and take a break if needed. There might not be food or drinks avaliable, so either be willing to go somewhere for them or bring your own. Bring a camera, you will probably want to take lots of pictures.
There will be rabbits for sale, so either have carrier (or 2) and cash or decide to not buy anything.
