It is certainly a possibility. However, since wifi in RV parts is not the same quality or same frequency from park to park you may be ok in one and not another. As a test I would configure your Phantom for flight, leave the aircraft on the ground or picnic table, take your RC with smart device (again connected) and go for a walk to see if you get any wifi interference. If you do not get any interference I would make some test flights at low levels, then go higher. One thing to be careful of is flying to close the the parks wifi access points/antennas. As close proximity could change the game.
