Thank you for the advice about the theft, I had not given it much thought. I've always used the lightest gauge cable from REI. I will invest in a U lock and only use our bikes for long trail rides. We had planned on visiting the mall and museums. The ride share bikes should be a good use for those days. Also I've never even seen a ride share program but I've read about them, it will be a valuable experience. Thank you for your tips, I would hate to lose my bike while on a bike vacation.
