Congratulations! That sounds like fun! Just a little jealous here...
The tank should still be holding water. It sounds like having the people there to move it is an issue, so I would just move it into the house where you want it and fill it maybe 1/3 of the way and watch for leaks. Add another third the next day, and top it off the third day. If it starts to leak, just drain it. Most likely it will be fine. Large glass tanks will sometimes have leaks around the top rim, so watch for that when it is completely full.
By the way, I used to use a garden hose to fill and drain my big tanks. To drain it, put the hose in the tank with a rock or brick to hold it down, turn the water on for 15 seconds, then take the hose off the spigot and it will drain pretty fast into the yard. If you have two or three hoses you can empty it in no time.
