Hi Ryan
Ischgl’s own website has a good range of apartments and private rooms that you can book through the TO. Also Skiline have a few.
But the resort is mostly a hotel or guesthouse place - so, it’s worth considering these too. A good tip though: check the location very carefully, because there are some hefty treks to the lifts otherwise.
As Richard says, Galtur and Kappl have cheaper options - but few apartments though really. Again, worth checking the guest houses here as lodging is cheaper than in Ischgl itself - but they are very quiet at night. Still, taxis are good value if a few of you going. If you do base yourself in Ischgl, these two are worth a day or half day visit for a change of scene and quieter slopes.
Great resort though - do go and report back!
