Im planning a trip to Austria with my fiancee for our third anniversary (of being together, not married of course) without the hotel and plane tickets, how much money should i take on an 11 day trip to austria cost? Planning on going to the Green Lake to swim or camp if possible and scuba dive is our main and only solid plan there. Dinners every night (which im not sure if hotel covers but we'll be eating dinner out now and then) but lets say we have dinner and lunch out every day, plus souveniers and shit you buy on vacations, maybe trips, rental car and gas?
