We are going on that TA.
We have sailed quite a few TA's. Love them!!
We have found the weather to be pleasant. Some days, shirt weather other days sweater and wind breaker.
Since you will be tired, I suggest you just arrive at the hotel, rest if need be and then just walk down the local streets. Many restaurants and cafes, stop, look at menus and see if locals are eating there. trust me, you will enjoy EVERYTHING, the food and the ambiance and the experience.
In regards to your hotel, look online and contact them. ask if you can pre check the luggage (then you know for sure) Im sure it will be yes.
