Hi Janice, depends where you’re going and your spending habits. Eastern Europe is cheap for both alcohol and good food when you find it. There are really cheap and a bit more money required options. I’ve travelled a fair bit, so if there are specific countries you’re thinking of going to, please ask. Central Europe especially Switzerland is expensive, so too are the Scandinavian countries. Your tour leader will normally recommend a range of places to eat/ drink.
Generally most trips include a continental breakfast, sometimes lunch and sometimes dinner, depending which trip you do. For a month I would recommend about 50-60 Euro/ a day. A lot of Eastern European countries have their own currency, which can get insane to manage as there values vary. For example in Czechia (Czech Republic) 50 Koruna equates to 3 Australian Dollars. They have notes upto 1000/ 2000 Koruna. And generally only accept cash in small amounts. The notes start at 5000 down to 100. So you can end up with a lot extra notes. Best to take out small (upto 500) at a time. There are ATMs everywhere. Exchanging can also be a pain from different non-EU currencies as their rates of exchange differ.
The tours normally indicate extra options and their costs in the tour details on the Topdeck website. So I’d recommend budgeting for these. Public transport, Uber and taxis are all fairly reasonable. I used Uber in Krakow in Poland last August, probably the easiest. Taxis in Bucharest are cheap. The trams in Prague are cheap as you can usually buy a bulk ticket. There are usually English instructions on the machines. Be careful not to ride for free (without a ticket) as I believe the fines are expensive.
Any questions, please ask
