Just wanted to say- we have done this quite a few times. With waiting for 7DMT- it depends on the CM's and when they let you on. Usually we get one to two rides. But last time, 7DMT was not working (in January). So do not be upset if all your plans go right just to get to 7DMT and either the CM doesn't let people on early-ish or it's not working. Good Luck!
