Good question. The best thing to do is drop me a mail with the details of what you are thinking of, and i can give you a proper quote.
I DO realise that some nice holidays/trips cost quite alot, so if my flight, accommodation and all other expenses are being taken care of, my quoted rate will reflect that. My rate is likely to reflect my likely usual bookings for that time period, rather than being based on a fixed amount per hour or day.
What you might also like to know is that i can get rather good discounts on hotels and holidays.. so if you fancy a trip, i could even save you money!! :)
