afaik, you could do it with one access point as long as everybody could 'see' it.

What you need to do is a sight survey. Take a router and take a laptop with wireless cabalities with you. connect the router and then configure the wireless card to the router. When you make a connection walk around see your weeks points you can then estimate how many access points you need.

Site survey is defintely required - I suggest however that one Access Point is unlikely to be enough. WLAN is a shared medium (a bit like an ethernet hub). Also, you can only expect roughly 50% real throughput compared to the speed of the WLAN - i.e 802.11b (11 Mb/S) gives roughly 5.5 Mb/S SHARED BETWEEN ALL CLIENTS on the channel (3 separate channels).
The same rules apply to 802.11G (it's on the same 2.4GHz spectrum) - although that allows up to 54 Mb/S - but over reduced distance.
802.11A allows up to 8 channels (at 5 GHZ), again at 54 Mb/S.
I would guess two APs would be right, with diversity omni-directional antennas, with them operating on different channels. Decent kit will allow best AP selection on a client basis, together with roaming.

Note also that laws governing WLAN use vary fom country to country.

Hope this helps,
