i spent the last year on the road living in a la quinta (quality... not!)
and yes.. their networks suck ass. 400 rooms, 200 rooms were for college kids, 300 to 400 kids just pounding myspace
solid... a 1Mbit line for 400+ people... 2.5Kbps avg.. nice

my solution? verizon wireless. no more wrestling for bandwidth. it just worked.
of course, if you want to connect multiple machines together, then you would need a box with dual nic cards.. one for lan, the other for your verizon wireless. and on the lan, use a hub, connect the other machine to it... and then use the first machine as a gateway

or... you could just get home that was my final solution...
