If Island have the same pricing policy for the Internet across both their ships then unfortunetly it wont be free. Prices ranged from around £4.50 for 30 mins to £18 for 4 hours whilst I was onboard the Island Escape in Oct. Wifi access was available in certain areas of the ship but not in the cabins although I think in the bigger suites wifi was available. Internet was very slow on board and I found using my 3G mobile was quicker whilst in dock. Cyber cafes' or fast food restaurants like McDonalds off a better wifi service tbh.
Thanks for the info, I'm desperate to stay in touch while away so might opt for the £18 option and hope for the best. Do you know if the wi-fi access on board was charged at the same rate?
