1) It's quite late to get up to the Upper Grindelwald glacier, if you arrive at 4 pm. You'll have to get to the footpath leading to the stairs first, and this takes a bus ride from the Grindelwald railway station. Next, it's another 15 minutes of walking before your reach the stairs, and then you have go get up too. Please note that the grotto itself seems to be closed, since the glacier has drawn back too much. According to the Grindelwald tourism website
, you can climb still the stairs though and take a look at the glacier gorge.
2) The Männlichenbahn is still closed down during your stay. Grindelwald, First, the Bachalpsee, the Lauterbrunnen valley with its waterfalls and Mürren are excellent alternatives.
3) Both are very different. Blausee is more of a family attraction, with a forest, a trout farm and boat rides over the lake. The Bachalpsee is a mountain lake with beautiful views, requiring a 1 hour walk from First. The hiking path will probably be open by mid-May, and if it is, my advice would be to go there instead of the Blausee.
