Hotel Wi-Fi networks with iPad

I have now loaded my personal and corporate email (Exchange)onto my iPad (bought in Apple store in SFO about 4-5 weeks ago). Ive been travelling and have my iPhone and old PC with me. I have stayed in three different hotels so far. I have not been able to connect to Wi-Fi with the iPad in any of three hotels. The iPhone hops on immediately, the PC has no issues. The iPad sees the networks but flatly refuses to join any Wi-Fi network. At home I have an Apple 802.11n router that the iPad has no issues with and has worked flawlessly. However, I bought the iPad to replace the heavy notebook PC that I have dragged aroun the world for the past few years. Its not working out. I'm pleased I brought the PC along with me or I would have been only able to access email through my iPhone.

I'm now in a hotel in the UK and again, no access to Wi-Fi (having wasted another hour of my life trying everything possible to get it working) So much for being the ideal travelling companion. I'm disappointed.
