If you're not cooking savvy but don't want to splash out on food during your stay, consider packing some instant meals – noodles are a great choice. You can use your hotel amenities like a kettle or coffee dispenser to boil the hot water. For bowls and cutlery, you can usually ask reception or the restaurant. Alternatively, you can bring your own. Pack a few different instant meals so you don't get bored, and voila, you have your meals set for the week.
Instant meals are, well, instant. They're fast and easy to make- and if you have a hot water flask, you can take it with you to cook on the go.
