Laptop internet access

We will be leaving next week on the Regatta - Lisbon to London. We have been on the old R2 and looking forward to seeing the ship again. We were on the Crystal Serenity and I was able to connect to the internet in our stateroom for a fee on my laptop. That way I could download email or other information and read it offline. It was not cheap but convenient. They experienced downtime also so you could not get the internet for a day or so. I want to get our stock information every market day. We were able to get our stocks on the TV in our room on the Celebrity Constellation for no charge. Donna
