Now that Monsters After Dark is done you will want to pull RSR first, Guardians second. RSR will run out first. But really as long as you do these two first (and as soon as you’re able to pull a second) you shouldn’t have to worry about either running out. This is assuming you are there at park opening.
Our last trip we rope dropped by the pier, used maxpass to book RSR and went first to walk on Toy Story (maybe 5min wait). Then rode GRR (it was warm that morning), then booked Guardians via maxpass. I want to say our return time for Guardians was around 11.
Another option would be to rope drop Guardians and get your FP for RSR first. Either via maxpass or grab a paper FP after riding Guardians. You can pull a FP for Toy Story later. I haven’t done this but have seen it recommended.
