B. Holiday messages

¹ one that will always be remembered (a memorable holiday is a strong collocation)
² extremely interesting
³ grand, making an impact
⁴ charming
⁵ hard to get to
⁶ unusually good

breathtaking views / scenery / pistes (ski slopes) [breathtaking (like stunning) suggests that something is so magnificent that it takes your breath away]
exclusive access / club / shops [only the most special people can use the facilities]
exhilarating feeling / ride / walk [makes you feel excited and full of energy]
exotic beauty / charm / location [unusual and more exciting than your everyday reality]
glamorous surroundings / film star / hotel [especially exciting and attractive]
luxurious cruise ship / accommodation / lifestyle [provides great comfort]
picturesque streets / villages / cottage [very pretty; attractive to look at – as pretty as a picture]
unspoilt charm / village / woodland [still in a beautiful and natural state]
unique opportunity / charm / facilities [so special it does not exist anywhere else]
