We have only been FT 2 years & love it! We had a VERY active first year. We crossed the US & visited many places in the SE. We spent 3 months in FL (1 mo in 3 different areas.). We made a big list by location of places we wanted to visit. Fabulous!
Year 2 was much quieter... We spent several months at the beach and then went south for the winter.
We found the tourist year to be expensive, but we knew it would be. We have found, for us, that we can afford a big tour year every other year. The off year, we still did some touring, but stayed in RV parks with activities we had not had the opportunity to enjoy while working: dancing, bingo, dominoes, pool, swimming, water aerobics, water volleyball, dinners etc. We didn't have time to be bored!
We plan our trips far in advance. We enjoy the planning and anticipation for what comes next... We don't boondock & stay in FHU places because we like it that way for now). We have found that staying in parks for 1 month gives us our best rate. We then have the $ to spend a few months each year for travel.
Talk to your spouse. Find out why she isn't excited. If you can't find a way to both enjoy it, you won't FT long...
