Does Emma Spears go to any parks, looking at her playlists she doesn't seem to, or only went to DVC park events, she just goes to resorts and Disney Springs and Orlando. She speaks well to camera, and has some personality, but okay in small doses, I think.
Helena and Martyn, I like them, but tone it down a bit with the catchphrases and pointing out where you got engaged, they've told us every vlog, we know. I like that they love DLP, and it's not fake.
David and Ian I'm most looking forward to for new vlogs. Their videos and filming, isn't the best, but I find I watch them for them. Their home vlogs of them just sitting on their couch, I could of found boring, but I just enjoyed watching them talk. I just wish they did more when in WDW, and would like longer vlogs from them, they've never fully done Epcot and all the countries, because of David's leg.
