My husband and I are taking a private tour. In several cities, our operator has arranged for us to have our own guide for the one full day that we will be in town. Since our itinerary is tight, that's probably a good idea. But could someone please tell me what the usual practice is when we want to stop for lunch, or to have a drink, or to just have some un-guided time to ourselves? Do guides expect to be invited eg to lunch, or do we offer an early tip so that they can make their own arrangements, or do they generally expect that they may be looking after themsleves? Obviously, if we're getting on well with a guide then we might all be happy with (and interested in) each other's company throughout the day. But I can imagine that there will also be times when we (and/or our guide) might welcome a bit of private down-time the many hours of sightseeing. We might also like to stroll around some streets or sights independently from time to time. Or we might want to treat ourselves to an expensive drink in an historic palace-type hotel. Or to visit shops of our choice (rather than his). Obviously, however, we wouldn't want to give any offence - so I'd be very grateful for any guidance on how best to handle such things..
