Santorini is a popular place with tourists, which means that there is a good selection of hotels to choose form. This is really good because it means there is likely to be something that will suit your needs. You do have to book in advance though, if you have specific requirements as it is a popular place and the best hotels will fill up quickly in the peak season.
Remember to be open minded and look at all of the accommodation options. You might be surprised at what you can find and how good it can be. You may feel safe with a particular brand of hotel or a particular types, but if you do not try different ones, you will never know what they are like.
Therefore, it is a good idea to think about the requirements you have of a hotel very early on. In fact, as soon as you have decided to go on holiday there, you should do this. Budget is likely to be the highest priority but even if you do not have that much money to spend, you want to make sure that you get good value for money. This means that you want to get the best that you possibly can. Think about your idea features of a hotel. You might like food served all day, all inclusive meals, entertainment, located so you can walk everywhere, swimming pool, family activities or a whole host of other things. Put together a list and then look at some of the hotels available and decide whether you want to amend your list.
It is important to put things in order of importance because you may not be able to get everything that you want from a hotel, especially if you have a small budget. However, be positive, a place like this does want to do its best for customers and so it is likely to offer a lot of good services.
Discuss it with the family/friends or your partner, whoever you are going with and find out what they all want and then come up with a short list of hotels which fit most of their requirements. Then talk again and you should be able to agree on which one would suit you all the best. The earlier you do it, the more choice you will have and therefore the best chance of keeping everyone happy.
