We will be arriving at Schiphol Airport ,needing to travel to the Convent Hotel in Amsterdam. I'm wondering what ,roughly,a taxi would cost? There will be 3 of us. We will have a foldable wheelchair for my Mom. Have a offer of prebooked transfer for $157.00 each way,but was wondering if we couldn't do better than that with a regular taxi . Thanks for all the help! Happy Traveling!
