I've not stayed at any of these hotels. However, here's some information about shuttles that might help.
Hawthorn Suites by Wyndham Orlando Lake Buena Vista:
According to their website, they offer a free shuttle departing at 8:30am, 11:10am, and 12:45pm. The returns are at 6:00pm, 8:00pm, and 10:30pm. Travel time is 45 to 60 minutes because they stop at other hotels.
This shuttle only goes to Epcot. To get to any other destination at Walt Disney World, you must transfer Disney transportation (bus, monorail). Personally, this sounds like a horrible set-up.

Wyndham Grand Orlando Resort Bonnet Creek:
I know virtually nothing about this place, as it doesn't fit my needs. I believe that the shuttles to theme parks is an additional charge.
Lots of people adore this property. You'll be able to find lots of information here:

Wyndham (and Garden) Lake Buena Vista Disney Springs Resort Area:
There are seven Disney Springs Hotels that share a shuttle bus system. Transportation to the parks starts 60 prior to regular opening with the last bus returning 90 minutes after park closing. Buses run every 30 minutes throughout the day. In my experience (from staying at some of the other Disney Springs Hotels), the buses are very punctual.
There are two sides ("A" and "B"). The Wyndham is on "B" along with the Best Western and Buena Vista Palace. Because these hotels are literally adjacent to each other, it usually only takes 2-3 minutes at each stop before the bus goes to the parks.
For each side, there are two buses that double up on parks. Typically, one bus goes to the Transportation and Ticket Center (for Magic Kingdom) and then to Disney's Animal Kingdom. The other bus goes to Epcot and then to Disney's Hollywood Studios.
Although it can be annoying to make a detour to a second park going or returning, it's not terrible. The entire route from the hotels to both parks and back to the hotels is usually completed within 30 minutes.
