This sounds very similar to one of my experiences. Take it with guarded enthusiasm and call it a thank you for not snooping or making her feel pressured. This is what a PMA will do for you. However, don't let the highs get too high. It sound like you are going with the flow and that is a good thing.
The trip to Vegas sounds great and my W and I did something similar at this phase of our "recovery" as well. That was the good news, the bad news is that she still contacted her "friends" for 2 or 3 months afterwards. It really pissed me off but remember this is a "process". A year later she is here with no contacting of "friends" and our R is in an upward spiral. Just do your best to get through the "crap".
Tip of the week: Get some massage oil and surprise her with an evening of pampering. Call it "positive reimforcement" for her seductress routine. Just portray youself as a quiet "cabana boy" and relax her into dreamland. The massage will probably make her "putty in your hands" but let her lead the evenings activties.
