Hi everyone, I know this is a popular topic on here. We will be in Europe for 12 days in Oct. I've been doing some research and I'm thinking that I won't buy any sim card or data. We will use Whats App or Messenger to stay in touch with family at home, we will be together so won't be calling each other. We are on a river cruise so will be partaking in their tours/excursions. There is wifi on the ship and hotels. Staying two nights before the cruise and one night after. We will need transportation to the airport but I have heard from others that the hotel will call you a taxi. I think it is $15 a day to add it to my current cell phone plan. So am I missing anything? Any reason I need a cell phone or data?
