It's also not a bad idea to rent someone someone to show you the ropes in case you run into problems. You can even rent a companion so that you have someone to talk to and have someone to hang out with to make a memorable moment.
It's has it's pro's and it's cons but if used effectively in could be a great resource in the long run. Feel free to look into the service and see if it's for you.
