PDA’s Banished To Oblivion This Half Term
While I can appreciate the reason for the apparently opt-in ban, it doesn’t make sense to me. I think it is a good idea for kids and parents to all carry phones to keep in contact when separated (either by design or accident). I also use my phone’s camera a lot. We’ve always had fun at theme parks with phone, digital camera, GPS, and all kinds of other e-gear that have actually enhanced the experience IMHO.
