СССРРРОООЧЧЧНННОО 40 БАЛОВ
Hello, Rosie.
I’m so pleased you can come surfing in July! Paul, Laura and Kevin are coming too, so there
will be five of us. We decided to return to New Sands, because the surf board hire is so cheap
there.
I’m starting to think about accommodation. We won’t camp again after last year! I hated
staying in a tent in all that rain!
Kevin wants to hire a caravan. There are some nice ones with 3 bedrooms, showers and cooking
facilities. The problem is, none of the caravan parks take short bookings in the summer. The
minimum stay is a week. It’s a shame because there are several nice parks near the beach.
There’s a youth hostel in New Sands. It’s the cheapest option after camping, and there is a big
kitchen and dining room where we can cook. The problem is, accommodation is in dormitories
and I don’t really want to sleep with strangers.
There are a few guesthouses in New Sands. Some have triple rooms, so we would only need to
book two rooms. They’re not expensive, but we wouldn’t be able to cook there. We would have
to eat out at restaurants, or eat sandwiches for every meal! We’ll have to book soon if we
choose that option, because many guest houses are already full. The hotels in New Sands are far
too expensive, even though I would love to stay at the Sunrise Pavilion with its rooftop pool!
The final option is to rent a cottage. Few cottages offer mid-week breaks in summer, but I found
one. It has three bedrooms - a double, a single and a twin, so two of us would have to share a
bed! There is a big kitchen diner with a microwave, washing machine and dishwasher. The
living room has a TV and DVD player. There is just one bathroom, but there is a separate WC.
There is a nice garden too. The problem is, it’s 5 miles from the beach, so we’d have to hire a
car, because there aren’t any buses.
Let me know which option you prefer.
Cheers Natalie
