in a running site need to change details in styling and functionality. ALL these points are in booking page and also partly customization of pinpoint plugin based custom development! you break it you pay it! 1. Days in calendar are coloured complete days not half for checkin and half for checkout. 2. Mention short dayname in main calendar on top. 3. Garage calendar (appears when option garage is checked) does not FOLLOW main calendar, if you make selection in September in main calendar, and check option garage it shows june. 4. Cleaning service for APT3 = 60 euro instead of 80 (find out estimate to revert to standard pinpoint extra services BOX, now is hardcoded) 5. Replace NAAM by Voornaam, replace Achternaam with Familienaam (booking page field names in NL - dutch) 6. Fieldorder in booking page information details. Correct order: Firstname, lastname, phone (is not translated! NL: telefoon // FR: Téléphone // DE: Telefon ), email, Street, Number, Postal code, City, country, message. 7. Button: "Indienen" replace with “Zend Aanvraag” in NL; in FR "Envoyer la demande"; in DE "Anfrage einreichen". 8. The confirmation message after sending a booking is not showing or does not contain the correct text, in this green box needs to be the text: "Your request has been succesfully submitted"; NL: "Uw aanvraag is succesvol verzonden"; FR: "Votre demande a été soumise avec succès"; DE: "Ihre Anfrage wurde erfolgreich eingereicht". 9.
