Travel / Touring Poland by Car & stay B&B: Pre-book or "wing-it"? [9]

Hi. Next March/April my husband and I will be leaving antipodean shores (Australia) for our first European holiday. We plan on arriving in Gdansk (ex CPH) and driving at a leisurely pace to south Poland - taking about 7-10 days using maps and Lonely Planet guides. We are yet to find a local travel agent with in-depth knowledge on Poland so we are reluctant to pre-book, preferring to find our own way. We of course will exercise common sense regarding safety - and will seek out English speaking operators when it comes to car hire & accomm. Although we live in the wide open space of rural Australia I have had experience driving in Kuala Lumpur (crazy drivers) & have driven on the "wrong side" of the road before in the US!. I was wondering if the major Polish cities/towns had easily locatable tourist offices where we could go to arrange accommodation, sightseeing, etc? Or is "winging it" a recipe for disaster?

Thanks too for your informative thread rjrogalla!
