We stayed a few years ago & requested first floor. Because our kids were younger at the time, I wanted a place to sit outside while they were napping or going to bed earlier. Having the patio was great for trips to the pool too…kids loved being able to run around on the grass in front. They would also hang on the patio while everyone was getting ready in the morning & see the lizards, ducks, etc. It felt like the patio extended the room a bit.
Third floor rooms have the balcony, which is also nice.
I don’t believe second floor rooms have a balcony, so consider that.
We didn’t find having to walk up stairs to the lounge difficult at all. It’s a small building, unlike some hotels with long corridors.
The lounge is on the pool end of the building, & we had a room close to that end, which also helped. But even if at the other end, it’s not that far to the lounge.
