Sure, a thousand generations will live and die along the way, but once we get over there, you've got stars every 0.1 ly or so, and with very plausible future tech, you could navigate between them in a few years. You could set up a proper starfaring, interplanetary civilization, with tradeships either going back and forth between two neighboring systems, or winding on long, never-repeating routes, visiting a dozen or so star systems in a human life.
(Most globular clusters appear to be old and metal-poor, and we haven't found a lot of planets there, and this only works if you find a globular cluster where ~every star can support a colony.)

Unless you're planning on forcing those thousand generations to live in inhumane conditions (e.g. force a static culture), that should probably be "if we get over there". I'd be very surprised if, after 1000 generations, the chance for arrival is > 50%.
It takes only one generation to decide not to go along, be that by changing course, or by not reproducing enough, or internal warfare, ...
