SPRI.NG IS IN THE AIR!

Welcome to our Spring Daybreak programme which continues the tradition of offering daytrips and tours at unbeatable value for money.  All the excursions in this brochure will be operated by Premier Travel Services Limited or Millers Coaches：both companies are part of the CHL Group，which owns Cambridge’S Cambus fleet.

小题1:____________________

Premier was established in 1936；the Company now offers the highest standards of coach travel in today’s competitive operating environment. Millers has an enviable reputation stretching back over the past 20 years，offering value for money coach services at realistic prices.  We’ve travelled a long way since our early days of pre—war seaside trips. Now our fleet of 50 modem coaches f few are more than five years old)operate throughout Britain and Europe but we’re pleased to maintain the high standards of quality and service that were the trademark of our founders nearly sixty years ago.

小题2:____________________

All Daybreak fares(unless specifically stated otherwise)include admission charges to the attractions，shows and exhibits we visit. Many full day scenic tours are accompanied by a fully trained English Tourist Board‘ Blue Badge’ guide or local experienced driver／guide. Some Daybreaks include lunch or afternoon tea. Compare our admission inclusive fares and see how much you save. The cheapest is not necessarily the best and value for money is guaranteed with Daybreaks. If you compare our bargain Daybreak fares beware—most of our competitors do not offer an all inclusive fare.

小题3:____________________

We value the freedom of choice，so you can choose your seat when you book. The seat reservation is guaranteed and remains yours at all times when aboard the coach.

小题4:____________________

In the interests of fellow passengers’ comfort, we kindly ask that smokers observe our ‘no smoking’ policy. On scenic tours and longer journeys，ample refreshment stops are provided when. of course，smoking is permitted.

小题5:_____________________

Do I need to book?

Booking in advance is strongly recommended as all Daybreak tours are subject to demand. Subject to availability，stand—by tickets can be purchased from the driver.

What time does the coach leave?

The coach departs from Cambridge Drummer Street(Bay 12)at the time shown. There are many additional joining points indicated by departure codes in the brochure. If you are joining at one of our less popular joining points，you will be advised of your pick up time(normally by telephone) not less than 48 hours before departure. In this way，we can minimise the length of pick-up routes and reduce journey times for the majority of passengers.

What time do we get back?

An approximate return time is shown for each excursion. The times shown serve as a guide，but road conditions can sometimes cause delay. If your arrival will be later than advertised. your driver will try to allow for a telephone call during the return journey.
