If you want to communicate with other attendees at my 30th birthday party, I suggest signing up for the free website and/or mobile application called "groupme" at https://groupme.com/ or through your phone's app store. This way, you can communicate with other attendees without needing to share your personal information and phone number with numerous people. It will be helpful for the occasions on which you want to plan a certain activity that I have not coordinated or if you are trying to find the group. Please let me know if you would like to be added to this groupme or simply join "Jenny's 30th Birthday Party" on groupme at: https://groupme.com/join_group/105927576/VBEEtcOW
My understanding is that the hotel rooms will be double queen rooms or king bed rooms, so many attendees may be looking for another person to join their room and save on the cost of the room. If you are interested in sharing a hotel room, travel, or anything else with another attendee but you are not sure who is available or looking for something similar, please feel free to reach out to me and I will connect you.
