A few minutes of internet browsing will let you know that this thread is the most up to date, informative thread on the LSS on the internet. The OP should be commended for making an attempt to promote discussion of the girls working here and the quality of service provided.
You will not find an encylopedic description of the girls and the services they offer at LSS on the internet. The LSS do not have their own (detailed) website, for many reasons I expect. Some reasons will be to do with the somewhat confused legality of saunas in Scotland and the fact that girls often only stay for a short while and reviews become redundant in a very little time. With regard to services, there are also issues regarding discretion which are easily understood by reading posts on this forum.
You state " should I ask her specifically what services she provides"? Er , well no, you will be sitting in a lounge area with several girls, possibly other punters. If you have a specific requirement, I suggest that you phone ahead and ask. Although, If I was Mona, I think I'd be taking May off as a holiday
A quick search of outcall rates on AW, shows that highly rated girls can be booked for £120-£150 per hour. Assuming that you can afford to travel from a country where "pay sex" is illegal, this should not be a problem for you.
I do wonder if you are genuine.
