Hey,
First of all, good luck to all of you taking the test soon.
Normally if you have taken the feast test already they can get a letter of declaration from that company. Feast is used by most European organisations and should only be taken once.
You will get some tests where you will have to make use of headings, don't remember in what format that test was anymore.
Leaving your baggage in the hotel is not a problem normally, Eurocontrol always uses that hotel during its testing phases so if you would already have to check out early they will probably still be able to accomodate for your luggage. small bags can always be stored in a few lockers at the reception.
Hope I have been of any help.
