Maka dalam penelitian ini melakukan perancangan prototipe high fidelity aplikasi Go on Vacation yang mana bertujuan sebagai solusi permasalahan pramuwisata dan wisatawan. Rancangan aplikasi menggunakan metode User Centered Design (UCD), dimana terdapat empat tahapan yaitu, understand context of use, specify user requirements, design solutions, dan evaluation against requirements. Untuk menguji prototipe aplikasi menggunakan usability testing dengan tiga buah aspek, yaitu efektivitas, efisiensi dan kepuasan pengguna. Hasil pengujian pada rancang prototipe aplikasi Go on Vacation menghasilkan persentase completion rate efektivitas sebesar 100%. Efisiensi dengan overall relative efficiency menghasilkan persentase rata-rata sebesar 100% dan kepuasan pengguna pengguna dengan menggunakan USE Questionnaire, menghasilkan persentase 89,08% untuk antarmuka pramuwisata dan 94,52% dari sisi antarmuka wisatawan.
