PM are not enabled on thsi forum, AFAIK. I find it hard to answer, because it depends on what activities you are planning for your party and where you are holding it. I have been using the limo for years. Uber may be cheaper than a taxi but i have not checked. The limo leave less observables tha a taxi Lyft or Uber.
Regardless i hope you enjoy your party. Have you contacted the lady(ies) you are interested in and/or made an appointment with the office?
