You have to have your bags delivered to the resort you are going to...in your case they have to go to the value resort. You can not have them delivered to the resort you are going to the next day. Of course, the value resort can have them delivered to your next resort, but you won't see those bags until late afternoon. So.....if I were you, I would not tag my bags, I would go to baggage claim and get them myself, and bring them on the bus with me.
Then, either have the resort move them to the next resort, or take a cab, with your bags to the next resort. It would seem that you want to be at a park bright and early, so a cab may not be a good idea.
This is how I handle moving to a new resort....
I get my bags to bell services very early in the morning. At a value you are better off taking them yourself, rather than waiting for bell people to come to your room and take the bags. Then I head to a park. Around mid-day, I head to the new resort, checkin. Sometimes my room has been ready, sometimes not. But, at least I've checked in. Then I grab a bite to eat and head out to a park again. Now, if you aren't picky about what room you end up in, you can forget about leaving the park midday...just head to the new resort at your leisure.
Your bags will get to the new resort some time after 5:00 that afternoon. Be sure to have anything you may need that day with you. I got stuck needing my bathing suit one time. It was brutally hot, I didn't want to be in the parks anymore, but my room wasn't ready and I would have loved to swim. But dopey me had left my suit in my bags that I had had moved. Duh!!
