Oh btw.... we picked Upper UK even though the site rental fee was about $50 more than Morocco because there are 7 tables with 4 chairs each already there.
I think if you choose any other locations and you want tables and chairs, you may have to rent them from Disney. I believe some locations like Lower UK have a couple of benches.
I'm not sure how much information you already have, but this is what ours comes out to (excluding services charges (20% of F&B) and taxes (6.5% of total including service charges))....
We have 40 guests (Upper UK is for 20 min to 50 max)
$325 - Site rental fee for Upper UK
$19.50 pp - The food and beverage minimum for Upper UK. I'm assuming that all locations have a F&B minimum, but I honestly only know that Upper UK is/was $19.50 as of December 2007- There are a number of minimums and fees that don't show up on the Disney Wishbook or anywhere else for that matter- We are not really happy about that and depending on how my first planning session goes next Monday "not really happy"

may turn into "REALLY MAD"!!
$12.95 pp (plus tax) - Illuminations Viewing Fee (All locations, applies to each guest who does not have an Epcot ticket for that day)
$440 (plus tax) Motorcoach (Our dinner reception is at The Attic at the Boardwalk Resort. It's a 5-10 minute walk to Epcot Upper UK. We asked if we walking was an option, we were told "NO", but I just re-read our contract and the motorcoach is NOT in our contract. We may use it anyway. Not sure yet.

No table & chair rental needed
