Hi Chris
You should be receiving your final information in the post any day now - this will give you details of excursions and prices so you can make your plans.
You'll also need money for one meal each day (usually lunch) plus drinks, tips, souvenirs etc.
Personally I would allow about £40-50 a day plus extra for excursions, but you may be someone who likes to spend more (or less) than that.
Most of the hotels will either have a room safe or a safe at reception where you will be able to leave any cash.
Have a great trip.
Kind regards,
Olly, your editor
