I would argue that the tuning fork is actually more work than the portal. Portals are completely in the DM's control - when they don't want to or aren't ready to do the planar adventure, they can just close it (temporarily or permanently), or tie its opening to a future cosmic event that the players can go gear up for, or they can have the entrance or exit move into the dungeon content they had previously prepared and so on. The tuning fork meanwhile puts the players squarely in the driver's seat - great if you have stuff ready to go for that plane at a moment's notice, not so much if life got in the way and the DM needs more than a long rest's worth of notice to get the planar session ready.
