Often only the downstream is shaped; if you have lots of p2p, you might want to ensure they do traffic shaping for upstream, too.
Where's your hotel? How'd you manage to get 100Mbit uplink? :-) Most hotels I've stayed at have either Cable (if it's 3* or below), or DSL / T1 (if it's something like 3*+ Hyatt Place), and they're all ridiculously slow.
