The drive from your townhouse to the parking lots of each Disney park should be relatively easy and quick - about 8 minutes to AK, 10 minutes to Epcot and HS, 13-15 minutes to the TTC for MK. However it is getting through the parking lot, tram (and monorail for MK), bag check line, etc. that you want to allocate additional time for in order to make rope drop. For MK, leaving 45 minutes prior to park opening got us there and through everything in time for rope drop and for the other parks leaving about 30 minutes prior to park opening was good (maybe a few minutes or so less for AK). Hope you have a wonderful trip, please report back on how things worked out for you and how you liked your townhouse. We stayed in a 3 bdrm Windsor Hills condo in May and had a great experience.
