Disagreed. Hotel points may be a good use for the expensive places like LON, MOW and Scandinavia, but, outside of the Old Town, Prague hotels are still reasonably priced. No problem finding a decent room for €70. Similarly, Vienna isn't facing a massive hotel shortage. Again, 4 stars for under €100 is easy, and if you *really* are on a budget, you could stay across the border in BTS for much less and take the train across (40 mins).
