Don't think the retuning to Intelsat 907 is an option for Duquesa Village as it requires a realignment of the dish and the purchase of a new decoder box. As the dishes are communal I'm sure you'd need community approval to move the dish, especially as any other users feeding off the same dish will lose their current package (even if that is only the couple of FTA channels left on sky) too unless they invest in the new box.
I don't think there are any reasonable options for TV without having an internet connection. but there are options to get internet without having to have a phone line (such as WIMAX 3/4g) available through orbit in Estepona. I heard something about a line of sight broadcast method if you can view an antenna on top of one of the mountains, not sure where to sign up though. To be fair I doubt the monthly subs are a lot cheaper than Movistar VDSL which is much quicker and lower setup.
Cheapest method if you only come for holidays is bring a USB drive full of previously downloaded Tv and films. There are plently of sites for downloading free. I bet a lot of holiday makers spend time around the port bars during the day using the free wifi to download last nights TV!
