i think option 3 is the best. last year when i went to HKG i made 2 days available to stay in Macau. everyone told me that 2 days is way too much for Macau. a day trip is more than enough. if you don't gamble 2 days is indeed boring in Macau. i would recommend you taking the speed boat that takes you directly to the Venetian Hotel. it is similar to the one in Vegas. have a lunch there, explore the surrounding area then head back to HKG. i did not stay at the LM. but W upgraded me to a Marvelous suite. it was indeed Marvelous.
The W is attached to a nice mall, there is a train Station in the mall. there is a train that takes you directly to the airport. actually you can check your luggage with the airline from the train station ( you don't have to check your luggage from the airport). check weather your airline has a counter located in the train station ( i saw many airlines including United, Air Canada, etc..)
also you can use other trains to go almost anywhere you want in HKG including Disney land.
option 3 is good.
