I'm not sure about convenience to the airport as I live only 2 hours away from Orlando & always drive.
Just as my opinion only, the Wyndham Palms is more of a resort that I would want to spend several days-week at, if I was only going to barely be at the hotel or resort & only 1 night, I wouldnt choose a resort.
With the Hawthorne, you would just walk down to breakfast with a short elevator ride or what ever but with how spread out the Wyndham Palms is, you may have to drive to the clubhouse, look for parking or take the golf cart shuttle for breakfast depending on where your unit is. I have read that the lines for breakfast at the Wyndham Palms is really long, only served poolside (does that mean no tables to eat at??) & only going by the sounds of it, it may only be a continental style breakfast (danishes, fruit, etc) also check out time at the Wyndham Palms is 10am (or you can request later if your are a by request member) breakfast is only served Mon-Fri at the Wyndham Palms (not sure the day of your stay.
The Hawthorne's breakfast at least has eggs, sausage & the other things. Also, if your stay is a Mon-Thurs, the Hawthorne has an evening managers reception with drinks & such (check their website for more details on this). Check the address for the Hawthorne, if its on Hospitality Way, then it is the newer one.
