Is there any way to connect my iPad to a hotel Internet connection via Ethernet ?
I don't think that it is possible to connect an Ethernet cable directly to the iPad, but I've seen people suggest Airport Express as a potential solution.
Yes there is but it takes some advance preparation. You need to purchase an Airport Express (US$99). It's necessary to use your computer once to set it up. Then, when you're at a hotel, you plug it into the available Ethernet connector.
Get any wifi router then hook that up to the hotel's ethernet. Then connect your iPad to the router using its wifi.
Please speak to hotel staff as connecting router may not be legal in all hotels/places.
Also remember not to plug cable from hotel socket into LAN, it should always go to WAN.
