I am going to Kettler tomorrow (and the Monty game 417 Row J) with my BIL and tyke to load up on shirts before heading to the game. Practice is at 10:15 so we will go then.
Player availability is generally good at Kettler, but you have to stalk the players. You often see fans waiting in the parking lot on the upper level; or can see players around the rink leaving the dressing room. Look for fans holding pens and the expensive cars in the lot. A lot of times you randomly run into someone you know - Locker or JoeB included. During rookie camps, you can see many players headed to the elevators headed down to the food court on the lower level.
It may well be worth it to go if making the trek from Sverige depending on how much of a hassle it is to get to Kettler. Make sure to check the practice schedule online - on the right hand side.
