Depending on where your room is, I think it takes 10-20 miinutes to walk to DTD and I would say it takes at least another 20 from there to crossroads.
Probably only cost you $5 for a taxi though.
we have stayed at the courtyard on hotel plaza blvd, now the holiday inn, and it was 5 minutes to DTD one way and 5 minutes to the crossroads the other way. but if it is 20 minutes from SSR to DTD you are probobly right
