I'm very grateful ! Your advices are useful and I hope that will help me on conversations. Thank you ! :)

Asking for information/help/service: e.g. "Could you call a cab/taxi for me?" e.g. "Could you help me with my luggage?" e.g. "Could you give me a wake-up call at 8am tomorrow?" e.g. "I have lost my room key. Could you help me open my room door please?" e.g. "The air conditioning isn't working in my room. Could you send someone up to fix it?" e.g. "May I know how I could access the internet here?" e.g. "Is this bottle of mineral water complimentary?" (complimentary = free) Checking out: e.g. "I would like to check out. I'm from room 202." e.g. "I'm sorry, but there's a mistake in the bill. I did not order room service." (in case they charged you for something you did not order) e.g. "Thank you so much. The service was wonderful. I had a pleasant stay here." e.g. "The service was awful! I would like to speak to your manager/supervisor." Hope this helps! Have a wonderful vacation! :)

Did you mean that you would like advice on phrases you can use at a hotel? :) When you're checking in: e.g. "I would like to check in. I have a booking for a single room under the name ____." (single room = a single bedded room ; double room = a big bedded room ; twin room = two bedded room ; suite = a luxurious room) e.g. "By what time do I have to check out?" (this ensures that you check out on time so you don't get charged an extra day at the hotel) e.g. "Do you have a map of the area?" (getting a map of the nearby area is helpful so you can explore around the hotel. It also ensures you have directions back to the hotel) Asking for directions inside the hotel: e.g. "Which way is the ..." - bar (a place where alcoholic drinks are served) - pool (a place where you can swim) - carpark (a place to park your car) - gym (a place to exercise) - spa - restaurant - lift - reception desk (a place to check in, check out, ask for information and help, etc.) Asking for directions to places outside the hotel: e.g. "May I know where the nearest train/bus station is?" e.g. "Do you know where I can buy souvenirs?" e.g. "Is there a movie theatre or cinema nearby?" e.g. "Do you know how to get to the ABC zoo?" e.g. "May I have directions to the XYZ mall?" Ordering room service: e.g. "I would like a serving of chicken nuggets sent to room 202 please." e.g. "Could you send someone up to service my room? I'm in room 202." (service a room = tidy up the room) e.g. "Can I have an extra blanket sent up to room 202?"
