Based upon what I've found it seems like there isn't a need to get tickets in advance for a train from Lucrene to/from Interlaken. We are traveling in late May. We are waiting to see what the weather is like before we decide when we are doing a day trip to Interlaken (vs. staying in Lucrene and going up the mountain).
Are we going to have any issues getting tickets for 4 on one of these hourly trains. Do they sell out? Sounds like there isn't much difference of views with different seating areas on this section of the Golden Pass.
Thanks.
