What are good things to pack if I am going to study spanish in Spain for a month?

For those who have experienced this…I am going for a month and I am doing the "Homestay" thing where you stay in the house of a spanish family..I will be going to Segovia.. also it would be helpful to know some things about Spanish customs that aren’t taught in school. Thanks!!
I will be going from end of June to end of July
Also is there anything nice that is good to give to your host family when you arrive?

mr_goura… had some good suggestions. I lived in Spain for 3 summers, so I’ll try to give you perspective about what you’ll need there. You will do a lot of walking, so take good comfortable shoes. Segovia is beautiful, can sometimes be a little windy, so may want to have a jacket on hand even though it’s summer. I’ve had a little trouble in the past with the plug converters for hair dryers, etc., so I recommend just buying a cheap one there if you need one. Your hosts will appreciate any gift really, but they usually enjoy something that represents home for you.

Be prepared to have a different meal schedule. Very small, light breakfast: hot chocolate or coffee and cookies for example. The lunch is a larger meal than you’re probably used to mid-day and you’ll get to try lots of great new foods, but it’s sometimes a little on the heavy side, especially in the summer. Be gracious and try to kindly express if the portions are too much for you. (this is why they siesta, you know) Dinner will come probably after 8 pm and be a little bit on the smaller side than lunch. As families, they usually eat slowly and converse quite a bit during mealtimes.

Youth are usually out late in the evenings at clubs and tapa bars.

Have a great time; Spain is wonderful.
