I did a week for $80. So far it works great in my room by the quiet pool and while at the sexy pool. Very pleased with how well it is working on my iPhone!
If you have to access a computer, the new wifi is much better than the old one. Still not great, but get off the computer and get me a drink.
Just returned... $15 a day (HELLO IT IS 2013...right?), but no problem at all with the service. It was fast and reliable. We were able to Skype back home and saw a couple on the beds next to the Sports pool doing the same one night. We were using a year old Android Tablet.
We decided not to bring the laptop this trip.. That way we wont be tempted to spent the $15 for internet lol.. We dont really need it anyhow.
