I agree with gillep. Everyone has different needs & preferences. Those will be influenced by the room category you have booked & your party make up. You have to figure out what is most important to your family. Some people want a day bed so make that their top request. Some want to be close to transportation. Some want close to the market etc. It is usually recommended you don’t ask for a specific room number, because if that room is not available, the assigner won’t know what it was about that room you wanted...location? sleeping arrangements? the view? etc.
Also remember, you don’t have to make room requests. If there is nothing you really, really need, don’t stress yourself out trying to pick the ideal location or room. We almost never make room requests. And the last time we did it was at POR, we didn’t get the building we requested anyway. So even if you do make requests, remember they are just that: requests & you may not get what you wanted anyway.
