Since you asked for a description of desserts and cordials I will tell you what we have seen in the last few trips.
Dessert offerings meant about 4-5 choices. We often saw two or more types of mousse in a chocolate cup--mousse basically means whipped cream with a flavoring of some sort--we had mango mousse, strawberry mousse, white chocolate mousse, kiwi mousse, etc. This was OK, but nothing too spectacular. Other offerings were fruit tarts, chocolate apple cake (weird choice). I have to say that there was never anything that was spectacular. They made a nice sweet bite before bed, but nothing to write home about, lol. I think that's why it's hard to remember, nothing really stood out if you know what I mean. There were Brownies on the kids table a few times, and the usual peanut butter cookies, chocolate chip cookies, and I think oatmeal cookies on there too.
Cordials were Kahlua, Baileys, Frangelico, Courvasier, that type of stuff, and on occasion there was a bottle of wine still left out after the evening wine and cheese hours during the late night cordial hours. (not often though) There is also a bottle of cream or milk to mix.
As to the room request mentioned, my first thought was that 1524 would be far from the lounge, although I am suddenly wondering if garden view room numbers come back towards the lounge...? Tikiman's sight has a map, I believe that should clear that question up though. I don't think there is a bad room on the first floor really.
