Maybe a bit too late, but I saw this and found the reactions a bit to easy. I'd say to tie her tight and keep scissors with you. You may be nice trying to be careful with tying her a bit too loose, but if she wants to be tight down, she doesn't want you to be careful. You may be letting her down by not tying her up right. Ofcourse, always keep it save and have scissors near, be sure they cut through the rope easily and she should be alright if you tie her too tight.
If i'm too late, I hope you had a wonderfull time.
Went to Scotland ones, anyone having that accent... It's just a real turn on ^^
