I'm curious as to what they said that made you feel pressured to do a 2hr cause I've never felt any pressure from any orgs when booking. Everytime I booked 2 hrs and up, it was my own choice. Unless, you were asking for a specific time and weren't getting the time you wanted, then yeah I'd see how you'd be pressured to book 2 hrs to secure that certain time slot.
My texts with SKS are usually straight forward and I've never had any problems with booking, I've gotten a slot everytime.
