Yeah man. I took a flight to Vientiane's. from the airport it's about a 15 to 20 minute ride into the centre. I stayed at Vientiane Backpackers Hostel. Good place. It's not far from the consulate which you will have to take a tuk tuk. And transport is more expensive in Laos. You shouldn't pay more than 50 000 kip one way, which I think is around 200 baht. But yeah just say visa and they know where to take you
