While I've had about 140-150 onsite stays, I've had probably around 80 offsite stays in all level hotels, rooms and suites and condo/timeshare units. I tend to look at Hilton for hotels because we were always Diamond but not a must.
First know that rates at offsite hotels are all over the place depending on your dates. I love the Embassy Suites Lake Buena Vista SOUTH, and while I've stayed for $100 a night I've seen it as high as $200 a night. I always look for a bargain. So when you have your dates, start playing at all kinds of places.
Second right now because of COVID most are halting their breakfasts and other free food, some are substituting bagged meals. Personally because we don't know what is happening, I would book not factoring that in. We've often found ourselves so much on the run we grab McD or CFA breakfast and eat in the car on our way to the park or I have stuff in room like muffins, yogurt, bagel and creme cheese.
Without knowing your budget here are some we have stayed at, were very happy with hotel & location and gotten great deals.
Lake Buena Vista (outside DS) along Palm Parkway is GREAT location for Universal and Disney. You take the back way to Universal and avoid I-4. Easy in to Disney as well as over the new bridge to outlets and all the new stuff there. Lots of spots to eat, grocery etc. I really like StayBridge Suites, Hampton Inn, Hilton Garden Inn, Homewood Suites. There are others there I have not stayed at. Like looks of Springhill Suites and Holiday Inn Express.
There is also a new Holiday Inn by Outlet Malls and I stayed at the Home2Suites which I liked.
I love Embassy Suites Lake Buena Vista SOUTH. I've stayed at the Hampton Inn LBV South and really liked the Queen/Queen Suite ... huge room with sofabed and seating area as well. Both are easy in to Disney without I-4.
Closer to Universal I've stayed a few times at Homewood Suites north of Convention Center, free parking and in middle of everything. Normal times is breakfast and some dinners. Lots of same level hotels all around it to give you a choice. Minutes to Universal and I could get to WDW parking lots in 15 minutes.
If you think you want to do both for sure stay between them and avoid 192 places.
