"Create a vibrant and playful cover for a children's travel journal titled 'Reisetagebuch für Kinder nach Mallorca'. The cover should feature cheerful, cartoon-style illustrations of iconic Mallorca landmarks, such as beaches, palm trees, and the Cathedral of Santa Maria of Palma. Include elements that appeal to children, like colorful drawings of a suitcase, a map, sunglasses, and perhaps a smiling sun. Use bright, inviting colors and a fun, easy-to-read font for the title. The overall design should be engaging and whimsical, reflecting the excitement of a child's travel adventure."
