Thank you very much for your usefull tip.
Apart from the 'reservations' tool it would be a good idea to provide a booking form in the home page, as this could boost direct sales.
I will seriously take this into considetration.
Thanks again for your help. I don't know whether a booking form in the home page can have a negative impact on Search Engine Spiders though.. Can anyone help with this?
