Reconfigure your Slingbox to use port 443. It is generally not blocked at hotels, cafes, and other public locations.

Unless you have remote access to your LAN network so that you can reconfigure your Slingbox and router its going to be difficult  to do I think but certainly using ports 443 and 80 are safer bets in general for getting through

However, you will need to configure logmein.com before you leave home.

Can you get access to your router remotely? If so, and if you have a router that can tanslate from one port to another, you can do this: 1.) Determine your WAN IP at home. 2.) Connect to your router remotely. Change the port forward rule so that instead of forwarding from your WAN IP on port 5001 to your Slingbox IP on port 5001, make the WAN port be 443. Leave the Slingbox port at 5001. 3.) In your SlingPlayer client, do a direct connection instead of using the finder. Enter your WAN IP in the box and type 443 as your Sling port. This should work and all should be well with the world again... :)

Maybe the easiest thing to do is switch hotels.  However, you should go to a local free wifi hotspot and see if you can connect remotely from there and make sure it isn't some other problem first. 

I've had good success with Hiltons (and related Hilton hotels).
