I’ve been on 2 Celebrity Ships in the past 2 months. The Wi-Fi on the Silhouette was pretty bad! I felt like I was being forced into upgrading to the premium just to get any service, but I didn't do it, and just tried it at different times. I really only use it to check my email and a few things online, but it constantly failed. The Wi-Fi on the Summit was better. I can’t say it was perfect but definitely an improvement from the past experience. Either way I would buy it and hope for the best. 😃
