Obergurgl is a bit of an oddity in that it consists of a cluster of largely 4* hotels at the head of the valley and not a lot else. There are few bars and restaurants outside hotels making it low key in the evenings. I have stayed at the Enzian, which is in a great location, a couple of times and am returning again this winter. Slope side pitstops are plentiful and pretty good and the Nederhutte on the home run can get wild after about 3pm, but there is a skidoo taxi to take you home if you can't get your skis back on. If you want something with a bit more of a pulse, Solden is a short bus ride down the valley and should satisfy even the most hedonistic.

Hi The buses between Obergurgl and Solden are very regular and reliable, at least they are in the Winter so I'm assuming that's also true in Summer. I don't think any accommodation in the area is likely to be cheap, but you may want to look at Bergresidenz Mühle, which is less expensive than most and sits between Obergurgl and Hochgurgl, with a bus stop right outside. My own German is very limited but I managed to get along quite happily there for a week, so you should be ok on that front. The locals are very friendly and many speak English.

Yes

We got the lift passes on the bus. We did research a bit before our holiday and they seemed to be the same as resort prices if I remember correctly. The added bonus being you have pass on arrival so are ready to go as soon as the lifts are open! You will need to give your tour operator a deposit for the passes - the passes then need to be handed back when you leave. Tis can actual been done to your hotel and not the lift pass place. This is very convenient.. I can't advise on ski hire I'm afraid we took our own equipment. My guess would be cheaper booked through package tour operator - but not sure.

Yes you can hire a guide either from the ski school in Obergurgl or Hochgurgl. We have had friends who did this

All reasonable prices. But had such a great breakfast we didn't need much lunch.
