CARose,
if you're not an elite I would recommend you get a local sim card instead. 1nt price at the hotel will cover 6 nts of data on a prepaid sim card. I actually opened 2 prepaids as I found out my first option didn't tether (yoigo) and was thus useless to me! I ended up with movistar. If you have an extra smartphone just set it up to tether and you'll be connected throughout Sevilla, not just the hotel!
