Dear EK Forum

Need your learned assistance please. I am QF Platinum (OW Emerald), however, do not have a lots of Dubai experience as have only ever been once in the past.
Going to Europe with QF/EK in July.
Have very little vacation time within a work trip, so attempting to minimise jetlag and have maximum rest.
Travelling from Sydney to Nice with a stopover for 4/5 days in Bangkok.
The choices of flights from BKK to DXB to NCE are:

EK373 / 31 Jul BKK/DXB 2120/0030
EK077 / 01 Aug DXB/NCE 0925/1415

or

EK377 / 31 Jul BKK/DXB 1525/1830
EK077 / 01 Aug DXB/NCE 0925/1415

My questions are:
1) Does EK offer a transit hotel for Business Class pax?
2) Am I better to have the shorter option 1, or a longer break in Dubai, option 2?

appreciate your advice.

thanks
