When I got my TT membership.. They offered me a free weekend Just for attending the sales pitch.. I went, prepared to say NO.. but the woman said to my wife and I "What would it take to get you to say YES?" Wife answered. and guess what.. They had it... Oh well. Since then i'm glad I did because during our lean years we spent half the summer and 2/3 the winter in TT parks.. for 45/month.
Only 30 amp (50 amp is more per night) but still beats paing the nightly/monthly fee at other parks in the area.
And of all the places I park,, The staff at the TT parks.. I've yet to find better.
