My Medicare advantage will reduce my premiums by 20% for July and August

5. Advantage provides at least the benefits of original medicare.

The Medicare website can compare plans, including original medicare, for costs. Most medicare advantage plans have a maximum yearly outlay, after which the plan pays 100%. Long term hospital care is covered to at least the extent of original medicare.
There are no limits in original medicare. Long term unskilled care is not covered by medicare or medicare advantage plans.
Many advantage plans also cover dental, vision, and/or drugs.
The main problem with advantage plans is that most arer HMO's or PPO's and do restrict providers. That hasn't been a major problem with any plan I have had.
