Try not to expect too much and you won't be dissapointed.
In my experience it was 20 minutes of infomation stretched into 6 hours. Make sure you do the online learning first. It is essential that you do this so that you can repeat it all again during the day. If you don't do it online first then you won't be able to suffer the boredom at the same level as everyone else.
On the plus side, there might be coffee and biscuits.
