We are staying in Disney in 5 weeks time and would like to buy 2 cheap phones to use in the parks. We are 2 families and there are two teenagers, who would like to seperate from us in the parks, so we would like to keep in touch with them. We will be going to Walmart the evening we arrive and could buy phones there. I think using our own UK phones would probably be expensive. Can anyone recommend any particular makes please?
