Dial-up internet access in Spain

Wasn't sure where to put this topic..

Anyway,
I'm going to Spain (Lanzarote) in two days and I will need internet access whilst there. Made an enquiery with the hotel, there isn't any WiFi in the room so my only option is dial-up
I found few websites containing settings and number(s) which to dial but I'm not quite sure whether they are legitimate or not. I don't want to end up with 100-150 euros bill for 5 hours surfing

Any helpful Spaniard around?

You might be better off, finding a cafe/coffee shop that has WiFi available. I expect that dial up would cost you a great deal to use.

What's your provider?

How long will you be there?

What do you need to use internet for and how much each day?

I need it for GW obviously (Canthan New Year)
I don't care about the ping. It can hit 1, 2, 3, 4k as long I can stay connected
I read somewhere that over the weekend it's 0.012 cents per minute. I don't know whether that's true or not
