Our lifestyle management service is provided by TenUK. Membership is normally £900 a year, but it is complimentary to Gold Card members. Eligibility is on the provision of making at least one travel booking through WEXAS a year and allows members to make up to 15 enquiries every 12 months.

Gold Card membership is £165 per annum.

Why would this TenUK membership cost £900 a year? Does it worth that much? Is it a good deal for £165 per annum?
