Go with very specific questions. They were able to help tell us how to do specific hikes, but were much less helpful when we asked for open ended recommendations on which hikes to do
Not an amazing experience. Rocked in about 5.30pm looking for advice on rafting - but was told that with 25 different companies, they couldn't advice and told me to walk around the streets asking, even though most were shut. Asked about accommodation, and they basically gave me the Slovenia Pension guide and told me to call around. Don't rely on this TIC to make stuff happen for you.
