You may be fine using the strategy of going early and riding later in the day also. You could buy an EP for a day or two if you need it once you get there.
I have been doing split stays lately with 2 nights at a resort with EP and then 3 at CBBR. I don't think AP hotel rates are out yet but they will appear and that will help. Be aware that they don't always release all room categories at the same time for AP rates though. I book something and keep checking daily until I find the room category I want. For example, my Feb trip I initially booked 5 night at CB, but all I could get an AP rate was for a family suite. Later I switched to 2 nights at a garden view room at PBH and 3 nights at CB, but still only suites were showing. Eventually I got a standard room at CB for those 3 nights (Mon-Thurs which are cheaper than the weekends) for $99 a night. I really like CB for the easy access to Volcano Bay.
One night at a resort with EP would give you 2 days of EP.
