Would this be right? Does it save a lot of time,
for the tag, you'll probably need to solve this with the DME, try to call them
saving time ?
pros : you don't have to wait for your bags at baggage claim in Orlando. You'll probably save 15 to 20 minutes, that's about the time you'll wait for your DME to depart. IMO it doesn't make much of a difference since you'll probably end up on the same bus anyway.
cons : you'll get your bags late, or when you come back from the parks, so you'll need to have everything ready, in your carry ons, for your first park day, plus you might worry about your bags (don't worry though, DME is quite reliable)
I'm trying to weigh up more time in MK on 1st day with how much I'll worry that bags arrive OK
If you do online check in 10 days in advance, specify that you'll be arriving early. You can choose the time of your earliest arrival. It can be 8am even though the check in time is supposed to be 3pm
We've done that 2 times in october and november, both at POP and CBR and our rooms were ready at 8am when we arrived at the hotel.
If your room is ready, just drop your baggage there, and off you go to the parks
if it's not ready, drop your bags at baggage services. You'll probably have to go to baggage services anyway, because you probably won't take your carry-ons with you to MK
So unless you don't have any carry on, it won't save you time to have your baggage picked up by DME vs getting them yourself.
In your situation, the only benefit I can see is not to have to haul your bags through MCO from baggage claim to DME counter, and from the hotel bus stop to the lobby then to your room. But you'll probably won't save time at all
