We are all thinking about our holidays this time of the year, so to help you prepare, here is the list of top things you must not leave without.
1 documents 5 guidebook
2 swimwear 6 money
3 medication 7 good book
4 sun lotion 8 clothes
a. An all important requirement that you must not forget, especially if it's prescribed as it might not be easy to get hold of abroad. The last thing you want is to feel ill or worried on your holiday.
b .This will save you a lot of time because you won't be deciding what you want to do for half the da ' before eventually agreeing on something. It's a great way to find out about the culture and traditions of the area that you are going to be staying in.
c. Please don't forget these, especially if your tickets and your passports are kept together with them!!!!
d .Remember not to pack too much! It's a good idea to lay everything out on your bed that you want to pack and then be really ruthless and only take what you really need!
e. Applicable to so many holidays as the weather does get hot sometimes and your skin can burn. Even if you're going on a ski holiday, you still need to bring it as the rays of the sun reflect off the snow making it even more dangerous.
f .Where would we be without at least some cash? Of course, you can take your credit card with you, but it is essential to carry a small amount of cash. Telephone calls, bottles of water, sweets, etc are all small purchases that are better paid with cash.
g .OK, so you will be on holiday, but that doesn't mean you have every moment planned. You may want to relax before going to bed. You can also read on the beach, or while travelling.
h. Nearly always essential even if you're not going to the beach, as some hotels in the cities might have swimming pools. You'll only envy the other people enjoying the water if you don't bring yours along.
