Prague, Czech Republic
The start time printed on our Viator reviews was off, so we almost missed it. (We were lucky that we showed up a full half hour early... just as the bus was leaving.)
The ossuary was really cool and made the trip worth it... we spent a fair amount of time in St. Barbara's too. I thought we should have been taken into the medieval silver mines, which we walked right by on the tour and would have probably been more interesting than the mint museum that we went to. If our tour group had been smaller, we probably could have done it, but there were about 40 people on our tour, which was too large and made us move quite slowly. (We spent 20 minutes on a bathroom break, then another 20 minutes on a second bathroom break.) The tour should have been split into two groups, especially since the tour was dual language English/Czech; they could have divided us into one English group and one Czech group.
This was a nice day trip from Budapest and well run. We had 8 people on our tour, which was the right size, and our guide was knowledgeable and spent the right amount of time explaining various rooms. We had 30 minutes of "free time" at the end, which was unnecessary because there was nothing really to do with the time. Overall I would recommend this tour.
The tour of Parliament was excellent and worthwhile, and we had a knowledgeable guide who explained something about Hungarian politics to us. We were lucky to arrive at Parliament just as the Hungarian Prime Minister was welcoming the Montenegrin Prime Minister outside, which was a nice ceremony to watch, and luckily they did not close down anything within Parliament because of it that we were supposed to see.
The city tour was just okay. I appreciated the history and the ease of getting from place to place. We went to the castle district and walked around slowly, but we did not get to go in anything, even though there was plenty of time to do so. (We were not given free time either, which would have allowed us to do that on our own and meet back.) It seemed somewhat wasteful... really, we just got a couple of views of the city. It would have been nice if something like St. Mattias Church had been included, because my husband and I ended up going back to the castle district just to see it. I would also recommend that future tours go to the citadel first, before going to the castle district, so that people who want to explore the castle more can stay awhile without skipping anything on the tour. It would also be nice to have us walk across the bridge, which is not very long, so that we really got the views of the city and the bridge, rather than just driving over it, and then take the funicular up to the castle district.
